SPI Interface
16.1.
Overview
The SPI is the Serial Peripheral Interface which allows rapid data communication with less
software interrupts. The SPI module contains one 8x64 receiver buffer (RXFIFO) and one 8x64
transmit buffer (TXFIFO). It can work in two modes: Master mode and Slave mode.
It features:
Full-duplex synchronous serial interface
Configurable Master/Slave
8x64 FIFO for data transmit and receive
Configurable Polarity and phase of the Chip Select (SPI_SS) and SPI Clock (SPI_SCLK)
Support Dedicated DMA
