8.1 UART Interface
The chip contains two enhanced (128 byte transmit FIFO and 128 byte receive FIFO, sleep mode, 127 Rx
and 128 Tx interrupt thresholds) UARTs named UART1 and UART2 compatible with the standard M16550
UART.
For UART1, only Rx and Tx signals are available (used for debug purposes).
UART2 features:
– standard HCI UART transport layer:
– RXD, TXD, CTS, RTS on permanent external pins
– 128-byte FIFOs, for transmit and for receive
– Default configuration: 57.600 kbps
– Specific HCI command to change to the following baud rates:

8.2 Synchronous Serial Interface
The Synchronous Serial Interface (SSI) (or the Synchronous Peripheral Interface (SPI)) is a flexible mod-
ule supporting full-duplex and half-duplex synchronous communications with external devices in Master
and Slave mode. It enables a microcontroller unit to communicate with peripheral devices or allows inter-
processor communications in a multiple-master environment. This Interface is compatible with the Motor-
ola SPI standard, with the Texas Instruments Synchronous Serial frame format and with National Semi-
conductor Microwire standard.
Special extensions are implemented to support the Agilent SPI interface for optical mouse applications
and the 32 bit data SPI for stereo codec applications.
8.2.1 Feature description: Agilent mode
One application is a combination of a Bluetooth device with an AGILENT optical mouse sensor to build a
Bluetooth Mouse. The AGILENT chip has an SPI interface with one bi-directional data port.
When spi_io from ADNS_2030 is driving, spi_rxd should be active, while spi_txd is set as a tri-state high
