3.2.20 Serial Port Peripherals

The F2812 supports the following serial communication peripherals:

eCAN: This is the enhanced version of the CAN peripheral. It supports 32 mailboxes, time stamping of messages, and is CAN 2.0B-compliant.

McBSP This is the multichannel buffered serial port that is used to connect to E1/T1 lines,

:phone-quality codecs for modem applications or high-quality stereo-quality Audio DAC devices. The McBSP receive and transmit registers are supported by a 16-level FIFO. This significantly reduces the overhead for servicing this peripheral.

SPI: The SPI is a high-speed, synchronous serial I/O port that allows a serial bit stream of programmed length (one to sixteen bits) to be shifted into and out of the device at a programmable bit-transfer rate. Normally, the SPI is used for communications between the DSP controller and external peripherals or another processor. Typical applications include external I/O or peripheral expansion through devices such as shift registers, display drivers, and ADCs. Multi-device communications are supported by the master/slave operation of the SPI. On the F2812, the port supports a 16-level receive and transmit FIFO for reducing servicing overhead.

SCI: The serial communications interface is a two-wire asynchronous serial port, commonly known as UART. On the F2812, the port supports a 16-level receive and transmit FIFO for reducing servicing overhead.

3.3Register Map

The F2812 device contains three peripheral register spaces. The spaces are categorized as follows:

•Peripheral Frame 0: These are peripherals that are mapped directly to the CPU memory bus. See Table 3-4.

•Peripheral Frame 1: These are peripherals that are mapped to the 32-bit peripheral bus. See Table 3-5.

•Peripheral Frame 2: These are peripherals that are mapped to the 16-bit peripheral bus. See Table 3-6.
