8.3 Connection Matrix Virtual Inputs

As mentioned previously, the Connection Matrix inputs come from the outputs of various digital macrocells on the device. Eight of the Connection Matrix inputs have the special characteristic that the state of these signal lines comes from a correspondin g data bit written as a register value via I 2C. This gives the user the ability to write data via the serial channel, and have this information translated into sig nals that can be driven into the Connection Matrix and from the Connection Matrix to the digita l inputs of other macrocells on the device. The I2C address for reading and writing these register values is at byte 0244. Six of the eight Connection Matrix Virtual Inputs are dedicated to this virtual input function. An I2C write command to these register bits will set the signal values going into the Connection Matrix to the desired state. A read command to these register bits will read either the original data values coming from the NVM memory bits (that were loaded during the initial device startup), or the values from a previous write command (if that has happened). Two of the eight Connection Matrix Virtual Inputs are shared with Pin digital inputs,(IO6 Digital or I2C_virtual_0 Input) and (IO7 Digital or I2C_virtual_1 Input). If the virtual input mode is selected, an I2C write command to these register bits will set the signal values going into the Connection Matrix to the desired state. Two register bits select whether the Connection Matrix input comes from the pin input or from the virtual register:

• reg <1074> Select SCL & V irtual Input 0 or IO6
• reg <1082> Select SDA & Virtual Input 1 or IO7 See table below for Connection Matrix Virtual Inputs.

8.4 Connection Matrix Virtual Outputs

The digital outputs of the various macrocells are routed to the Connection Matrix to enable interconnections to the inputs of other macrocells in the device. At the same time, it is possible to read the state of each of the macrocell outputs as a register value via I2C. This option, called Connection Matrix Virtual Outputs, allows the user to remotely read the values of each macrocell output. The I2C addresses for reading these register values are at bytes 0240 to 0247. Write commands to these same register values will be ignored (with the exception of the Virtual Input register bits at byte 0244).

9.0 Combination Function Macrocells

• Three macrocells that can serve as either 2-bit LUTs or as D Flip Flops;
• Five macrocells that can serve as either 3-bit LUTs or as D Fl ip Flops with Set/Reset Input;
• One macrocell that can serve as either 3-bit LUT or as Pipe Delay;
• One macrocell that can serve as either 2-bit LUT or as Programmable Pattern Generator (PGEN);
• Five macrocells that can serve as either 3-bit LUTs or as 8-Bi t Counter / Delays;
• Two macrocells that can serve as either 4-bit LUTs or as 16-Bit Counter / Delays. Inputs/Outputs for the 17 combination function macrocells are configured from the connection matrix with specific logic functions being defined by the state of NVM bits. When used as a LUT to implement combinatorial logic functions, the outputs of the LUTs can be configured to any user defined function, including the following standard digital logic devices (AND, NAND, OR, NOR, XOR, XNOR). 9.1 2-Bit LUT or D Flip Flop Macrocells There are three macrocells that can serve as either 2-bit LUT s or as D Flip Flops. When used to implement LUT functions, the 2-bit LUTs each take in two input signals from the connection m atrix and produce a single output, which goes back into the connection matrix. When used to implement D Flip Flop function, the two input signals from the connection matrix go to the data (D) and clock (clk) inputs for the Flip Flop, with the output going back to the connection matrix. The operation of the D Flip-Flop and Latch will follow the functional descriptions below:
• DFF: CLK is rising edge trigger ed, then Q = D; otherwise Q will not change
• Latch: when CLK is Low, then Q = D; otherwise Q remains its previous value (input D has no effect on the output, when CLK is High).

SLG46537_DS_108 Page 82 of 192 SLG46537 9.7 4-Bit LUT or 16-Bit Counter / Delay Macrocells There are two macrocells that can serve as either 4-bit LUTs or as 16-bit Counter / Delays. When used to implement LUT function, the 4-bit LUT takes in four input signals from the Connection M atrix and produces a single output, which goes back into the Connection Matrix. When used to implement 16-Bit Counter / Delay function, four input signals from the connection matrix go to the external clock (ext_clk) and reset (DLY_in/CNT_Reset), Keep and Up for the counter/delay, with the output going back to the connection matrix. These two macrocells have an optional Finite State Machine (FSM ) function. There are two ma trix inputs for Up and Keep to support FSM functionality. Any counter within Green PAK is counting down by default. In FSM mode (CNT/DLY0 and CNT/DLY1) it is possible to reverse counting by applying High level to Up input. Also, there is a possibility to pause counting by applying High level to Keep input, after the level goes Low, the counter will proceed counting.These macrocells can also operate in a one-shot mode, which will generate an output pulse of user-defined width. These macrocells can also operate in a frequency detection. Delay time and Output Period can be calculated using the following formulas:

• Delay time: [(Counter data + 2) / CLK input frequency – Offset*];
• Output Period: [(Count er data + 1) / CLK input frequency – Offset*]. One Shot pulse width can be calculated using formula:
• Pulse width = [(Counter Data + 2) / CLK input frequency – Offset*]; *Offset is the asynchronous time offset between the input signal and the first clock pulse. For timing diagrams refer to section 9.8 CNT/DLY/FSM Timing Diagrams. Both of these macrocells can have their active count value read via I2C. See Section 19.5.1.2 Reading Counter Data via I2C for further details.

• CNT/DLY0 must be set to Wake an d Sleep Controller function (for all ACMPs);
• Register WS => enable (for each ACMP separately);
• CNT/DLY0 set/reset inpu t = 0 (for all ACMPs);
• In case of using OSC1 (25 MHz), OSC0 must be set to Force Powe r On. As the OSC any oscillator with any pre divider can be used. The user can select a period of time while the ACMPs are sleeping in a range of 1 - 65535 clock cycles. Before they are sent to sleep their outputs are latched so the ACMPs remain their state (High or Low) while sleeping. WS controller has the following settings:
• Wake and Sleep Output State (High/Low) If OSC is powered off (Power Down option is selected; power down input = 1) and Wake and Sleep Output State = High, the ACMP is continuously on.

Figure 49. WS controller

SLG46537_DS_108 Page 98 of 192 SLG46537 If OSC is powered off (Power Down option is selected; power down input = 1) and Wake and Sleep Output State = Low, the ACMP is continuously off. Both cases WS function is turned off.

• Counter Data (Range: 0 - 65535) User can select wake and sleep ratio of the ACMP; counter data = sleep time, one clock = wake time.
• Q mode - defines the state of WS counter data when Set/Reset signal appears Reset - when active signal appears, the WS counter will reset to zero and High level signal on its output will turn the ACMPs on. When Reset signal goes out, the WS counter will go Low and turn the ACMPs off until the counter counts up to the end Set - when active signal appears, the WS counter will stop and Low level signal on its output will turn the ACMPs off. When Set signal goes out, the WS counter will go on counting and High level signal will turn the ACMPs on while counter is counting up to the end.
• Edge Select defines the edge for Q mode High level Set/Reset - switches mode Set/Reset when level is High Note: Q mode operates only in case of "High Level Set/Reset”.
• Wake time selection - time re quired for wake signal to turn the ACMPs on Normal Wake Time - when WS signal is High, it takes a BG time (100/550 µs) to turn the ACMPs on They will stay on until WS signal is Low again. Wake time is one clock period. It shoul d be longer than BG turn on time and minimal required comparing time of the ACMP. Short Wake Time - when WS signal is High, it takes a BG time (100/550 µs) to turn the ACMPs on. They will stay on for 1 µs and turn off regardless of WS signal. The WS signal width does not matter.
• Keep - pauses counting while Keep = 1
• Up - reverses counting If Up = 1, CNT is counting up from user selected value to 65535. If Up = 0, CNT is counting down from user selected value to 0.

15.0 RC Oscillator (RC Osc)

The SLG46537 has three internal oscillators. RC Oscillator that runs at 25 kHz / 2 MHz (OSC0), Oscillator that runs at 25 MHz (OSC1) and Crystal Oscillator. It is possible to use all three oscillators simultaneously. The fundamental frequency can also come from clock input (IO15 or IO17 for 25 kHz / 2 MHz and IO14 for 25 MHz or Crystal OSC), see Section 21.0 External Clocking. 15.1 25 kHz/2 MHz and 25 MHz RC Oscillators There are two divider stages that allow the user flexibility for introducing clock signals on various Connection Matrix Input lines. The predivider allows the selection of /1, /2, /4 or /8 divide down frequency from the fundamental. The second stage divider (only for 25 kHz / 2 MHz Oscillator) has an input of frequency from t he predivider, and outputs one of seven different frequencies on Connection Matrix Input lines <27> (OUT0) and <28> (OUT1). See Figure 66 and Figure 67 below for details. There are two modes of the POWER CONTROL pin, (reg<1658> for 25 kHz / 2 MHz OSC and reg<1657> for 25 MHz OSC):

• POWER DOWN <0>. If PWR CONTROL input of oscillator is LOW, the oscillator will be turned on. If PWR CONTROL input of oscillator is HIGH the oscillator will be turned off and OSC divider will reset.
• FORCE ON <1>. If PWR CONTROL input of oscillator is HIGH, the oscillator will be turned on. If PWR CONTROL input of oscillator is LOW the oscillator will be turned off. The PWR CONTROL signal has the highest priority. The SLG46537 has a 25 kHz / 2 MHz OSC FAST START-UP function re g<1338> (1 – on, 0 – off). It allows the OSC to run immediately after power-up this decreases the settling time. Note that when OSC FAST START-UP is on, the current consumption will rise. The user can select two OSC POWER MODEs (reg<1343 for 25 kHz / 2 MHz OSC and reg<1341> for 25 MHz OSC):
• I f AUTO POWER ON <0> is selected, the OSC will run when any macrocell that uses OSC is powered on.
• I f FORCE POWER ON <1> is selected, the OSC will run when the SLG46537 is powered on. OSC can be turned on by:
• Register control (force power on)
• Delay mode, when delay requires OSC
• CNT/FSM

17.0 Power On Reset (POR)

The SLG46537 has a power-on reset (POR) macrocell to ensure cor rect device initialization and operation of all macrocells in the device. The purpose of the POR circuit is to have consisten t behavior and predictable results when the VDD power is first ramping to the device, and also while the VDD is falling during power-down. To accomplish this goal, the POR drives a defined sequence of internal events that trigger changes to the states of different macrocells inside the device, and finally to the state of the I/O pins.

17.1 General Operation

To start the POR sequence in the SLG46537, the voltage applied on the VDD should be higher than the Power_ON threshold VDD voltage must ramp up to the operational voltage value, but the POR sequence will start earlier, as soon as the VDD voltage rises to the Power_ON threshold. After the POR sequence has sta rted, the SLG46537 will have a typical period of time to go through all the steps in the sequence (noted in the datasheet for that device), and will be ready and completely operational after the POR sequence is complete. The SLG46537 is guaranteed to be powered down and nonoperationa l when the VDD voltage (voltage on VDD) is less than Power Off Threshold (see in Electrical Characteristics table), but not less than -0.6 V. Another essential condition for the chip to be powered down is that no voltage higher (see Note 2) than the VDD voltage is applied to any other PIN. For example, if VDD voltage is 0.3 V, applying a voltage higher than 0.3 V to any other PIN is incorrect, and can lead to incorrect or unexpected device behavior. Note 1:The Power_ON threshold is defined in Electrical Characteristics table. Note 2: There is a 0.6V margin due to forward drop voltage of the ESD protection diodes. To power down the chip the VDD voltage should be lower than the operational and to guarantee that chip is powered down it should be less than Power Off Threshold. All PINs are in high impedance state when the chip is powered down and while the POR sequence is taking place. The last step in the POR sequence releases the I/O structures from the high impedance state, at which time the device is operational. The pin configuration at this point in time is defined by the design programmed into the chip. Also as it was mentioned before the voltage on PINs can’t be bigger than the VDD, this rule also applies to the case when the chip is powered on.

17.2 POR Sequence

The POR system generates a sequence of signals that enable certain macrocells. The sequence is shown in Figure 77. environmental factors, such as: slew rate, VDD value, temperature and even will vary from chip to chip (process influence). Figure 77. POR sequence

21.0 External Clocking

The SLG46537 supports several ways to use an external, higher accuracy clock as a reference source for internal operations.

21.1 Crystal Mode

When reg<1136> is set to 1, an external crystal can be connected to IOs 13 and 14 for supplying an accurate clock source. See section 16.0 Crystal Oscillator. An external clocking signal on IO14 can be used in place of t he crystal. The high and low limits for crystal frequency that can be selected are 32.768 kHz and 40 MHz.

21.2 IO17 or IO15 Source for 25 KHz / 2 MHz Clock

When reg<1358> is set to 1, an external clocking signal on IOs 15 or 17 will be routed in place of the internal RC oscillator derived 25 kHz/2 MHz clock source. When reg<1355> is set to 0, IO17 is in use, when set to 1, IO15 is in use. See Figure 66. The high and low limits for external frequency that can be selected are 0 MHz and 77 MHz.

21.3 IO14 Source for 25 MHz Clock

When reg<1357> is set to 1, an external clocking signal on IO14 will be routed in place of the internal RC oscillator derived 25 MHz clock source. See Figure 67. The high and low limits for external frequency that can be selected are 0 MHz and 84 MHz.
