– 14 – CXN1000 ∗ For details of the contents below, see the specifications of the BlueCore 2-External (equivalent to the CXD3251GL) made by CSR. Software Stack The CXN1000 features a 16-bit RISC microcontroller which runs a software stack complying with Bluetooth specifications ver. 1.1. The following are the three software stack options to integrate into the CXN1000. 1) HCI Stack The HCI stack enables the layers up to the host controller interface (HCI) to be executed by the on-module RISC microcontroller. It is considered to be the most common stack configuration with general-purpose capabilities. All layers above HCI are handled by the host processor. HCI Stack Configuration LC Baseband microcontroller PCM I/O Host I/O 32K-byte RAM LM HCI Radio Host Flash memory UART USB

– 15 – CXN1000 RFCOMM Stack Configuration The RFCOMM stack enables the layers up to RFCOMM to be executed by the on-module RISC microcontroller. Then, the amount of processing is reduced on the host processor. 3) Virtual Machine Stack LC PCM I/O 32K-byte RAM LM L2CAP RFCOMM SDP UART USB Baseband microcontroller Radio Host Host I/O Flash memory 2) RFCOMM Stack Virtual Machine Stack Configuration LC PCM I/O 32K-byte RAM LM L2CAP VM application software RFCOMM SDP UART Baseband microcontroller Radio Host Host I/O Flash memory

– 16 – CXN1000 The Virtual Machine stack eliminates the need for a host processor. The applications and Bluetooth stack can be run on the integrated RISC microprocessor using a application execution environment called Virtual Machine (VM). In order to develop applications, the BlueLab TM software development environment (SDK) and Casira development kit supplied by CSR are required. Inquire for further details.

– 17 – CXN1000  External Interfaces UART Interface The UART interface makes it easy to communicate with other serial devices using the RS-232 standard∗ CXN1000 UART_TX UART_RX UART_RTS UART_CTS UART Pins As shown in the figure above, four signals are used to execute the UART function. When the CXN1000 is connected to another digital device, data is transmitted between the two devices using the UART_RX and UART_TX signals. The remaining two low active signals, UART_CTS and UART_RTS, can be used for RS-232 hardware flow control. All the UART pins are configured as CMOS I/O pins. Their signal levels are 0V and V DD 3.0. The baud rate, packet format and other UART configuration parameters are set using PS Tool or other BlueCore software. Note:In order to communicate with UART at the maximum data rate using a standard PC, a serial port adapter card with acceleration must be installed in the PC. ∗1 The RS-232 protocol is used, but the voltage level is from 0V to VDD 3.0. (An RS-232 transceiver IC must be externally attached.) UART Settings Parameter Baud rate Flow control Parity Number of stop bits Bits per channel Possible values 1200 baud (≤2% error) 9600 baud (≤1% error) 1.5M baud (≤1% error) RTS/CTS or none None, odd or even 1 or 2 Minimum Maximum

– 18 – CXN1000 Break Signal With the UART interface, the CXN1000 can be reset as soon as a break signal is received. As shown in the figure below, the break is identified by the continuous low logic level in the UART_RX pin. Resetting occurs if t BRK is longer than the value defined by PSKEY_HOST_IO_UART_RESET_TIMEOUT (0x1A4) persistent store key. The system can be initialized to a known status from the host using this function. The CXN1000 can also send break characters that can be used for starting the host. The frequently used baud rates and the values of the PSKEY_UART_BAUD_RATE (0x204) persistent store key linked to those rates are shown in the table below. These standard values are not necessarily required conditions, and all baud rates within the range supported can be set by the persistent store key with the following equation. Baud Rate = UART_RX tBRK Standard Baud Rates PSKEY_UART_BAUD_RATE 0.004096 Baud rate 1200 2400 4800 9600 19200 38400 57600 76800 115200 230400 460800 921600 1382400 Error 1.73% 1.73% 1.73% –0.82% 0.45% –0.18% 0.03% 0.14% 0.03% 0.03% –0.02% 0.00% –0.01% Hex 0x0005 0x000A 0x0014 0x0027 0x004F 0x009D 0x00EC 0x013B 0x01D8 0x03B0 0x075F 0x0EBF 0x161E Dec 157 236 315 472 944 1887 3775 5662 Persistent store value

– 19 – CXN1000 USB Interface The USB pins of the CXN1000 support a full speed (12Mbps) USB interface. They enable direct drive of the USB cable, thereby obviating the need for an external USB transceiver. With this interface, the CXN1000 can operate as a USB unit and respond to requests from a PC or other master host controller. The interface supports both OHCI and UHCI standards. It also complies with Bluetooth specifications Ver.1.1 and part H2. Although USB is a system that is capable of both master and slave operations, the CXN1000 supports USB slave operations only.

– 20 – CXN1000 Serial Peripheral Interface (SPI) When data is sent or received through the SPI pins, the CXN1000 uses 16-bit data and 16-bit addresses. Through these pins, data is transmitted and received while both the internal processor is operating and it has stopped operating. Data is written or read one word at a time unless the auto increment function is used to access blocks.

– 22 – CXN1000 PCM Interface The PCM interface of the CXN1000 supports the continuous transmission and reception of PCM data using hardware. This reduces the overhead of processors for wireless headset applications. The CXN1000 provides a bidirectional digital audio interface that is connected directly to the baseband layer of the on-chip firmware. The bidirectional digital audio interface does not pass the HCI protocol layer. Data can be transmitted and received with one or more SCO connections using the hardware of the CXN1000. The PCM interface supports up to three SCO connections at a time. The CXN1000 can operate as the PCM interface master for generating an output clock of 128, 256 or 512kHz. Alternatively, when it is set to serve as the PCM interface slave, it can operate using an input clock up to 2048kHz. The CXN1000 can support many different clock types including long frame sync, short frame sync and GCI timings. In terms of 8k per second sampling, the CXN1000 supports 13- or 16-bit linear, 8-bit µ-Law and 8-bit A-Law companding sample formats. The PCM settings can be performed using the PSKEY_PCM_CONFIG (0x1B3) persistent store key.

– 23 – CXN1000 PCM Interface Master/Slave When the CXN1000 is set as the PCM interface master, PCM_CLK and PCM_SYNC are generated. PCM Interface Master When the CXN1000 is configured as the PCM interface slave, PCM_CLK rates up to 2048kHz are accepted. PCM Interface Slave 128/256/512kHz 8kHz CXN1000 PCM_OUT PCM_IN PCM_CLK PCM_SYNC PCM_OUT PCM_IN PCM_CLK PCM_SYNC Up to 2048kHz 8kHz CXN1000

– 24 – CXN1000 PIO Port The parallel input/output (PIO) port serves as the general-purpose I/O interface of the CXN1000. It consists of nine programmable bidirectional I/O lines. These programmable I/O lines can be accessed via either the installed application run by the CXN1000 or the private channel or manufacturer-designated HCI commands. PIO[3]/USB_WAKE_UP ∗1 This multi-functional terminal is a programmable I/O line. Either the programmable I/O or USB_WAKE_UP function can be selected with the PSKEY_USB_PIO_WAKEUP (0x2CF) persistent store key setting. PIO[4]/USB_ON ∗1 This multi-functional terminal is a programmable I/O line. It can also be used as the USB_ON function. PIO[5]/USB_DETACH ∗1 This multi-functional terminal is a programmable I/O line. It can also be used as the USB_DETACH function. PIO[6]/CLK_REQ This is a multi-functional terminal whose function is determined by the persistent store keys. Using PSKEY_CLOCK_REQUEST_ENABLE (0x246), it can be set to low when the CXN1000 is in deep sleep and to high when a clock is requested. If a shift in the timing in certain operation modes is to be avoided, the clock must be supplied within 4ms from the PIO[6] rising edge. PIO[7] Programmable I/O terminal PIO[8] Programmable I/O terminal PIO[9] Programmable I/O terminal PIO[10] Programmable I/O terminal PIO[11] Programmable I/O terminal 1 The USB function can be mapped in the software to any of the PIO terminals.
