3.4.13 Serial Peripheral Interface (SPI) Module

The Serial Peripheral Interface (SPI) module is a high-speed, synchronous serial I/O port that allows a serial bit stream of programmed length (1 to 16 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 controller and peripheral operation of the SPI. The port supports a receive and transmit FIFO for reducing servicing overhead.

The SPI guides are:

For devices not listed above, refer to the device-specific technical reference manual.

Table 3-60 lists the SPI types, including device-specific differences within each type.
