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 BlueLabTM software development environment (SDK) and Casira development kit supplied by CSR are required. Inquire for further details.

CXN1000
* External Interfaces UART Interface The UART interface makes it easy to communicate with other serial devices using the RS-232 standard1.
CXN1000
UART_TX 30 UART_RX 29 UART_RTS 31 UART_CTS 32
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 VDD3.0. 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 VDD3.0. (An RS-232 transceiver IC must be externally attached.) Parameter Baud rate Flow control Parity Number of stop bits Bits per channel UART Settings Minimum Maximum 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 8

CXN1000
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 tBRK 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.
tBRK UART_RX
Break Signal 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. PSKEY_UART_BAUD_RATE 0.004096

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.
- 19 -
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.

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 -Law and 8-bit A-Law companding sample formats. The PCM settings can be performed using the PSKEY_PCM_CONFIG (0x1B3) persistent store key.

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_UP1 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_ON1 This multi-functional terminal is a programmable I/O line. It can also be used as the USB_ON function. PIO[5]/USB_DETACH1 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.
