Software Stack

The CXN1000 features a 16-bit RISC microcontroller which runs a software stack complying with Bluetooth

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

In order to develop applications, the BlueLab^TMsoftware development environment (SDK) and Casira

The UART interface makes it easy to communicate with other serial devices using the RS-232 standard .

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.

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.)

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.

The frequently used baud rates and the values of the PSKEY_UART_BAUD_RATE (0x204) persistent store

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 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.

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

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.

1

PIO[4]/USB_ON

This multi-functional terminal is a programmable I/O line. It can also be used as the USB_ON function.

1

PIO[5]/USB_DETACH

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.

The USB function can be mapped in the software to any of the PIO terminals.
