Bluetooth V1.2 Class 2 Module
Data Book
3.2 USB
This Bluetooth module contains a full speed (12Mbit/s) USB interface that is
capable of driving a USB cable directly. No external USB transceiver is required.
The device operates as a USB peripheral, responding to requests from a master
host controller such as a PC. Both the OHCI and the UHCI standards art
supported. The set of USB endpoints implemented can behave as specified in
the USB section of the Bluetooth specification v1.2 or alternatively can appear as
a set of endpoints appropriate to USB audio devices such as a set of USB
speakers.
Since USB is a master/slave oriented system (in common with other USB
peripherals), This Module only supports USB slave operation.
3.3 SPI (Serial Peripheral Interface)
BlueCore3-Multimedia External uses 16-bit data and 16-bit address serial
peripheral interface, where transactions may occur when the internal processor
is running or is stopped.
The BlueCore3-Multimedia External is the slave and receives commands on
SPI_MOSI and outputs data on SPI_MISO.
1 Reset the SPI interface
2 Write the command word
3 Write the address
4 Write or read data words
5 Termination
Hold SPI_CSB high for two SPI_CLK cycles
Take SPI_CSB low and clock in the 8 bit command
Clock in the 16-bit address word
Clock in or out 16-bit data word(s)
Take SPI_CSB high
3.4 Kalimba DSP
The Kalimba DSP is an open platform Kalimba DSP allowing signal processing
functions to be performed on over-air data or CODEC data in order to enhance
audio applications.
