3.2.22 Serial Port Peripherals

The F281x and C281x support 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:

The multichannel buffered serial port (McBSP) connects to E1/T1 lines, phone-quality

codecs for modem applications or high-quality stereo audio DAC devices. The McBSP

receive and transmit registers are supported by a 16-level FIFO that 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 F281x and C281x, 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 F281x and C281x, the port supports a 16-level, receive-and-

transmit FIFO for reducing servicing overhead.
