This reduces the microcontroller loads significantly, thus gaining more performance for other tasks, even if slower microcontrollers ar e used. A variety in fields of application is given by different packaging*1 and configuration options.

5 Functional Description

5.1 Clocking

The IC is clocked by connecting an external 14.7456 MHz quartz at the XTAL1 and XTAL2 pins. It is possible to daisy chain or directly connect multiple CCE4510 chips to the CLK pin for clocking. The CLK pin is then connected to the XTAL1 pin of the other chip(s). Clock feed through is enabled by default and can be disabled by pulling the CLK_EN pin high. References: Oscillator, Pin Descriptions

5.2 Operational Modes

There are three possible operational modes for each CCE4510 IO-Link Channels - Standard I/O, UART and Frame Handler Mode. The channel mode can be configured in the MODE register.

5.2.1 Standard I/O (SIO)

If a channel is configured in the Standard I/O Mode, the mode of the output stage is freely configurable. The SIO register allows the user to choose between a N, P or Push-Pull driving mode via the DRV bits. The TXEN and TXD bits of this register enable direct control over the output driver. The RXD bit in the MISO Status Nibble reflects the current state of the CQ pin. In this mode, it is also possible to control and observe the channel using the TXEN, TXD and RXD pins. The corresponding pin and register values get logically ORed. Therefore, either the unused pin or register values should be zero, to allow control via the desired interface. Since the sense of TXD to CQ is inverted, it is possible to connect a standard microcontroller UART interface with a high idle state to the TXD/RXD pins. References: SIO1/2, MISO Status Nibble. Pin Descriptions

5.2.2 UART

If a channel is configured in UART Mode, the output stage is set into Push-Pull Mode and the output cannot be controlled via the SIO register or the external pins. It is required to define the used COM speed in the MODE register. By default, the channel will listen for incoming UART transactions at the CQ pin. If a character is received, an interrupt is triggered and the data can be read back from the UART register. A transaction is started by writing the data to the UART register. The received UART data is not buffered. Receiving multiple characters, while not reading them back, causes data loss. This will be indicated by the OFLW bit in the MISO Status Nibble. References: UART1/2, MODE1/2, MISO Status Nibble

5.2.3 Frame Handler

The Frame Handler Mode extends the UART interface. Like in UART mode, the output stage is set into Push-Pull Mode and the output cannot be controlled via the SIO register or the external pins. It is required to define the used COM speed in the MODE register. It mostly automates the transaction of frames, defined by the IO-Link protocol. Therefore, an automated CRC check for incoming and an automated CRC computation for outgoing me ssages is integrated. The frame handler will also monitor the specified timing constraints and takes care to comply with them as well.

5.2.3.1 Configuration

The operational mode as IO-Link Master or Device can be set via the MAS bit in the FHC register. This register also allows the user to relax the timeout detection or to disable the automatic CRC computation. The master and device message lengths of each frame are influenced by the OD, MPD and DPD registers, but are also depending on the access type, addressed channel and frame type which are defined in the second byte of each IO-Link frame. FT0 frames always use one byte on-request data. FT1 frames use the MPD or DPD lengths, if the address channel is the Process Data Channel, otherwise the OD length is used. FT2 frames always use the MPD, DPD and OD lengths.

5.2.3.2 Master Mode

If configured as master, the frame handler waits for the user to write the complete message data into the frame buffer via the FHD register. This can be done by multiple SPI transactions or by a single bulk SPI transaction. By default, writing the last byte of a message into the buffer will start the transaction and the message CRC is automatically generated. If the automatic CRC feature is disabled, the transaction will start immediately after the first byte is written into the frame buffer. There is also the possibility to start a new frame transaction with respect to the defined cycle time in the CYCT register or even synchronizing various CCE4510 IO-Link channels using the sophisticated synchronization mechanism. If a frame was transmitted successfully, the frame handler will start listening for any incoming device data and triggers an interrupt after a part or the complete device message is received. The interrupt behavior can be modified using the IMSK and TRSH register. Parity or checksum errors during the transaction will be indicated by the MISO Status Nibble. The received data can be read back via the FHD register by multiple SPI transactions or single/multiple bulk SPI transactions.

5.2.3.3 Device Mode

Configured as device, the frame handler listens for incoming master transactions and triggers an interrupt, if a part or the complete device message is received. The interrupt behaviour can be modified using the IMSK and TRSH register. Parity or checksum errors during the transaction will be indicated by the MISO status nibble. The received data can be read back via the FHD register by multiple SPI transactions or single/multiple bulk SPI transactions.

IO-Link Master PHY with integrated Frame Handler Datasheet Revision 1.7 24-AUG-2021 CFR0011-120-00 14 of 39 © 2021 Dialog Semiconductor After successfully receiving an incoming master message, the frame handler waits for the user to write the complete message data into the frame buffer via the FHD register. This can be done by multiple SPI transactions or by a single bulk SPI transaction. The transaction always starts immediately after the first byte is written into the frame buffer. RE CE IVE T RA NSMITIDLE transmission done reset triggered reset triggered start of master message first by te of device message buffered Figure 5: Device Mode Sequence References: Additional IO-Link Features, Serial Peripheral Interface, FHD1/2

5.2.3.4 Skip and Reset Function

It is possible to reset the frame handler or skip an invalid frame from any state. This can be done by writing one to the RST or the SKIP bit of the FHC register. Skipping a frame causes the frame handler to ignore the rest of an incoming message, without triggering any additional interrupt. A soft reset is done after receiving the rest of invalid message or if a timeout was detected. Skipping a frame has no effect on the cycle timer. Resetting a frame will immediately reset the frame handler into its idle state and also causes a reset of the cycle timer. When resetting the frame handler with the RST bit or skipping a frame with the SKIP bit, all other bits written to the FHC1/2 register within the same SPI frame will be ignored. References: FHC1/2

5.3 Interrupt Handling

The chip utilizes two modes of interrupt handling. The active mode can be switched with the IMODE bit in the INT register. Interrupt Mode 1 is active by default.

5.3.1 Mode 1

Interrupts are triggered on rising edges of the WURQ, RXRDY, TXRDY or TOUT bits in the SPI Status. If CQ is configured as input in SIO mode, interrupts are also triggered on any edge of the RXD bit. Changes of the STATE bits in the SPI Status also trigger interrupts depending on the IMSK register settings. Trigger conditions can be the start of frame transmission or reception or reaching a defined fill level of the buffer. An interrupt is always triggered after a frame is completely received. Another trigger condition is any change of values in the STAT register. Therefore, the microcontroller should always deal with an interrupt by reading back the STAT register. The interrupt is cleared while reading the status register. References: MISO Status Nibble, STAT, IMSK1/2

5.3.2 Mode 2

The interrupt triggering conditions are the same as described in Interrupt Mode 1. Mode 2 differs in the way how interrupts are handled.

IO-Link Master PHY with integrated Frame Handler Datasheet Revision 1.7 24-AUG-2021 CFR0011-120-00 15 of 39 © 2021 Dialog Semiconductor First, the interrupt origin can be determined by reading the INT register. The interrupt then needs to be actively cleared by the user. This is done by writing a one to the appropriate bit ISTAT, ICH1 or ICH2 in the INT register. The INTX pin will remain in its active state until all interrupts are cleared. References: MISO Status Nibble, STAT, INT, IMSK1/2

5.3.3 Interrupt Masking

To reduce the number of triggered interrupts in frame handler mode, the user can deactivate the triggering of interrupts at certain conditions in the IMSK register. All frame handler interrupts are listed in Table 4. Table 12: Frame Handler Interrupts Interrupt Name Description SOT Start of Transaction Interrupt Triggers when the chip starts transmitting its message SOR Start of Reception Interrupt Triggers as soon as the chip starts receiving a message LVL Message Level Interrupt Triggers if a defined amount of buffered characters is reached MSG End of Message Interrupt Triggers after the last character of a message was received CYCT Cycle Time Interrupt Triggers when the configured cycle time has passed The MSG interrupt is always active. By default, all other interrupts are masked. If the LVL interrupt is active, an interrupt will be triggered if the input buffer reaches a defined fill level. The current amount of buffered characters can be queried in the BLVL register. The threshold for buffered characters which triggers the LVL interrupt is configured in the TRSH register. Cycle Time Master Message Device Message SOT SOR LVL MSG CYCT SOR LVL MSG SOTDevice Mode Master Mode Figure 6: Interrupt Trigger Positions It is also possible to mask the short detected (SD) interrupt of the STAT register. Otherwise an interrupt gets triggered as soon as a short is detected. References: Frame Handler, IMSK1/2

5.4 Protection Features

The CCE4510 IO-Link Master PHY integrates various features to protect the IO-Link master and connected IO-Link devices. Different configuration options allow the user to take indivi dual safety measures and to prevent damage.

5.4.1 Current Sensing

5.4.1.1 Internal/External Mode

There are two possible methods implemented to detect a high load at the IO-Link supply voltage – an internal and an external current sensing mechanism. Both mechanisms cannot be active at the same time. The user must choose, which one should be used for each channel. The current sensing mode is configured by the SDINT bit in the CFG register. The SD bit in the STAT register and the SDX pins always reflect the current sensing state. The internal current sensing mechanism does not need any external circuitry to work but has the limitation to only detect currents IMHS and IMLS at the CCE4510 CQ pin with a fixed current threshold. High currents IDEV from a connected device cannot be detected. Therefore, the short protection feature for devices is not feasible in this mode. However, the usage of an external NMOS transistor is still possible. The external current sensing can detect high currents IMHS and IMLS at the CQ pin and IDEV of a connected device. External shunts with a typical resistance of 0.5 Ω need to be applied for a current threshold of 400 mA. It is possible to adjust the high current detection threshold by changing the shunts resistance value. The voltage drop over the shunt is defined with 200 mV. Current sensing over a shunt and an external NMOS transistor allow the usage of the short protection feature. IMHS IMLS IDEV MASTER DEVICE LP CQ LM Figure 7: High Current Detection References: Current Sensing, Application Notes, CFG1/2

5.4.1.2 Overload/Short Protection

The Overload Protection protects master and device from high loads at the channel output CQ. The output driver of a channel is automatically disabled if high currents are detected for a time > t OVLDDET. The channel stays disabled and gets re-enabled after a time tOVLDDIS. If the high load at CQ still persists, the channel will be disabled again. This high current polling reduces the power dissipation of the chip and reduces the risk of overheating. The feature can be used in conjunction with the internal and external current sensing. Timing is configured in the OVLD register. It is also possible to disable this feature. The short protection feature detects shorted or defective devices and disables their power supply, if NMOS transistors are used for power supply switching. If a high current is detected for a time > tSHRTDET, the gate driver gets disabled and the device is powered down. The gate driver stays disabled but can be switched on again manually by the user. The feature can only be used in conjunction with the external current sensing. Timing is configured in the SHRT register.

The IO-Link specification allows high currents while powering on a device. To avoid automatic disabling of the gate driver during power-on, tSHRTDET should be configured > 50 ms. Time can be reduced again after the power-on phase. References: OVLD1/2, SHRT1/2, STAT

5.4.2 Voltage/Temperature Monitoring

The chip is equipped with a voltage monitor that observes the VCC supply voltage of the chip and a temperature monitor which observes the die temperature. By default, the chip is configured to automatically disable all channels if the die temperature is too high or the VCC supply voltage is out of range. The monitor states can be read back from the PROT register. The automatic protection feature is also controlled via the PROT register. References: Monitoring Thresholds, PROT

5.5 Additional IO-Link Features

5.5.1 Automated Wake-Up

Before starting the automated wake-up procedure, the following configuration needs to be applied:

SIO mode selected in the MODE register
Output driver enabled (TXEN = 1 in the SIO register)
If external gate driver is used: enable external gate driver (GEN = 1 in the CFG register)
SYNC and CRC bit of the FHC register configured with default values Writing a one to the WURQ bit in the SIO register will then start the automated wake-up procedure. If the procedure is active, the WURQ bit is set to one and can be aborted by writing a one to the WURQ bit. During the procedure, the chip is set into frame Handler mode and runs the wake -up procedure an interrupt is triggered and the chip stays in IO-Link mode. If a timeout is indicated, the procedure failed. Otherwise the chip is configured, and the detected COM mode can be read back using the Mode register. References: MODE1/2, SIO1/2, FHC1/2, CFG1/2

5.5.2 Cycle Timer

A cycle timer is available for channels configured as frame handler in master mode. It enables the user to comply with the configured IO-Link cycle times without further effort. The cycle time is set up in the CYCT register. The format of this register resembles the defined structure in the IO -Link.

IO-Link Master PHY with integrated Frame Handler Datasheet Revision 1.7 24-AUG-2021 CFR0011-120-00 18 of 39 © 2021 Dialog Semiconductor It is possible to configure cycle times that are shorter than 400 µs. Although this is not recommended, since the standard states 400 µs as minimum cycle time (IO-Link Spec v1.1, A.3.7). If the register is zero, the cycle timer gets disabled. When the cycle timer is active, a new master message transaction will not start until the configured cycle time has passed. If the cycle time is over and no new data is available to start the message transaction, the EOC bit in the MISO Status Nibble will indicate the end of a cycle. It is possible to reset the frame handler without resetting the cycle timer by triggering a soft reset, using the SKIP bit in the FHC register. The cycle timer will be reset together with the frame handler when a hard reset is triggered using the RST bit in the FHC register (see 5.2.3.4 Skip and Reset Function). References: CYCT1/2, MISO Status Nibble, FHC1/2

5.5.3 Channel Synchronization

The CCE4510 provides a synchronization feature that can be enabled by the SYNC bit in the FHC register. If enabled, TXD (SYNC) and RXD (CYCT) pins are used for synchronization purposes and do not have their default behavior in frame handler mode. The CYCT pins indicate if the cycle time has passed with a high level. It is also possible to enable the cycle time interrupt for a channel over the CYCT bit in the IMSK register. If this interrupt is enabled the TOUT bit in the MISO Status Nibble is also used to indicate the end of a cycle. The channels will wait for start of transmission until a configured cycle time has passed, the output buffer is filled and the SYNC pin is toggled or a synchronization request is triggered over the SYNC register. These requests can be broadcasted to different chips, specifically triggering different channels on each chip by using the SMSK register. This gives a fine granularity for synchronizing channels, even over multiple chips. For the best possible accuracy, it is highly recommended to control the synchronization via the dedicated pins. Table 13: Sample Configuration Chip MODE1/2 FHC1/2 CYCT1/2 SMSK IC1 0h0A / 0h0A 0h0E / 0h0E 0h14 / 0h00 0h09 IC2 0h0A / 0h0A 0h0E / 0h0E 0h14 / 0h00 0h09 IC3 0h0A / 0h0A 0h0E / 0h06 0h00 / 0h00 0h04 As an example, we have three CCE4510 chips with the configurations from Table 13. If we broadcast a synchronization request via SPI by writing a one to the ST1 bit in the SYNC registe r, channel 1 from IC1 and IC2 will start their transaction as soon as the configured cycle time has passed. If we write a one to the ST2 bit of the sync register, channel 2 of IC1 and IC2 and channel 1 of IC3 will start their transaction immediately. References: SMSK, SYNC, Pin Descriptions

5.5.4 LED Drivers

The chip integrates a LED driver for each of the two channels. The LEDs are controlled by the LSEQ and LHLD registers. There are various ways of influencing the timing of a blinking sequence. It is also possible to synchronize the LED blinking sequences over each channel or various chips. This is done by writing one to the SYNC registers PRE and LED bits. The user can choose between two driver strengths of 5 mA or 10 mA using the ILED bit in the CFG register. As an example, writing LSEQ 0hCC and LHLD 0h80 will resemble the specified blinking sequence for channels that operate in IO-Link mode, starting with the “LED off” state (IO-Link Spec v1.1, 10.9.3).

5.6 Serial Peripheral Interface

5.6.1 Transaction Format

The CCE4510 is configured as SPI slave and uses the CPOL=0, CPHA=0 configuration. During each transaction, a minimum number of two bytes must be transferred. For bulk access to the frame handler buffers via the FHD1/2 registers, n bytes can be transferred. The first byte after a falling SSX edge always reflects the current state of the two channels. The format depends on the configured modes. Figure 10: SPI Timing Diagram
