The SPI module is a master/slave high-speed synchronous serial input/output interface that allows a serial bit stream of programmed length (2 to 16 bits) to be shifted in and out of the device at a programmed bit-transfer rate. There are four separate SPI modules (SPI0, SPI1, SPI2, and SPI3) in the device. All these four modules support up to two external devices (two chip selects) and are able to work as both master and slave. The SPI module allows multiple programmable chip-selects. It is normally used for communication between the device and external peripherals. Typical applications include interface to external I/O or peripheral expansion via devices such as shift registers, display drivers, SPI EEPROMS, and analog-to-digital converters. The SPI module may be used to connect to serial flash memory devices for booting. The SPI module supports EDMA events and can be used in conjunction with EDMA for data transfer with minimal CPU overhead.
The SPI module has the following features:
The SPI module allows software to program the following options:
The SPI module does not support the following features:
