For details of the contents below, see the specifications of the BlueCore 2-External (equivalent to the  
CXD3251GL) made by CSR.  
Software Stack  
The CXN1010 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 CXN1010.  
1) HCI Stack

UART  
Host I/O

PCM I/O  
HCI Stack Configuration  
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.

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.

Virtual Machine Stack Configuration  
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 R software development environment (SDK) and Casira  
development kit supplied by CSR are required. Inquire for further details.

External Interfaces  
UART Interface  
1
The UART interface makes it easy to communicate with other serial devices using the RS-232 standard .  
CXN1010  
UART_TX 29  
UART_RX 30  
UART_RTS 28  
UART_CTS 36  
UART Pins  
As shown in the figure above, four signals are used to execute the UART function. When the CXN1010 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.)

CXN1010  
With the UART interface, the CXN1010 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 CXN1010 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.

CXN1010  
USB Interface  
The USB pins of the CXN1010 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 CXN1010 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 CXN1010 supports USB  
slave operations only.  
Serial Peripheral Interface (SPI)  
When data is sent or received through the SPI pins, the CXN1010 uses 16-bit data and 16-bit addresses.  
Through these pins, data is transmitted and received while the internal processor is operating and not  
operating. Data is written or read one word at a time unless the auto increment function is used to access  
blocks.

PCM Interface  
The PCM interface of the CXN1010 supports the continuous transmission and reception of PCM data using  
hardware. This reduces the overhead of processors for wireless headset applications. The CXN1010 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 CXN1010.  
The PCM interface supports up to three SCO connections at a time.  
The CXN1010 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 CXN1010 can support many different clock types including long frame sync, short frame sync  
and GCI timings.  
In terms of 8k per second sampling, the CXN1010 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.

CXN1010  
PIO Port  
The parallel input/output (PIO) port serves as the general-purpose I/O interface of the CXN1010. 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 CXN1010 or the  
private channel or manufacturer-designated HCI commands.  
PIO[0]/RXEN  
This multi-functional terminal is a programmable I/O line. Either the programmable I/O or control output for  
external LNA (if fitted).  
PIO[1]/TXEN  
This multi-functional terminal is a programmable I/O line. Either the programmable I/O or control output for  
external PA Class1 applications only.  
1  
PIO[2]/USB_PULL_UP  
This multi-functional terminal is a programmable I/O line. Either the programmable I/O or PIO or USB pull-up  
(via 1.5kresistor to USB_D+).  
1
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 CXN1010 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.
