2.5.22 Serial Port Peripherals

The devices support the following serial communication peripherals:

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 MCU 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. The SPI contains a 4-level

receive and transmit FIFO for reducing interrupt servicing overhead.

SCI:

The serial communications interface is a two-wire asynchronous serial port,

commonly known as UART. The SCI contains a 4-level receive and transmit FIFO

for reducing interrupt servicing overhead.

I2C:

The inter-integrated circuit (I2C) module provides an interface between a MCU

and other devices compliant with Philips Semiconductors Inter-IC bus (I2C-bus)

specification version 2.1 and connected by way of an I2C-bus. External

components attached to this 2-wire serial bus can transmit/receive up to 8-bit data

to or from the MCU through the I2C module. The I2C contains a 4-level receive-

and-transmit FIFO for reducing interrupt servicing overhead.

eCAN:

This is the enhanced version of the CAN peripheral. The eCAN 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 the DMA to

significantly reduce the overhead for servicing this peripheral. Each McBSP

module can be configured as an SPI as required.

USB:

The USB peripheral, which conforms to the USB 2.0 specification, may be used as

either a full-speed (12-Mbps) device controller, or a full-speed (12-Mbps) or low-

speed (1.5-Mbps) host controller. The controller supports a total of six user-

configurable endpoints—all of which can be accessed via DMA, in addition to a

dedicated control endpoint for endpoint zero. All packets transmitted or received

are buffered in 4KB of dedicated endpoint memory. The USB peripheral supports

all four transfer types: Control, Interrupt, Bulk, and Isochronous. Because of the

complexity of the USB peripheral and the associated protocol overhead, a full

software library with application examples is provided within ControlSUITE™.
