6.14 Serial Peripheral Interface (SPI)
6.14.1 Overview
The Serial Peripheral Interface (SPI) is a synchronous serial data communication protocol that
operates in full duplex mode. Devices communicate in Master/Slave mode with the 4-wire bi-
direction interface. The NuMicro^® M0519 series contains up to three sets of SPI controllers
performing a serial-to-parallel conversion on data received from a peripheral device, and a
parallel-to-serial conversion on data transmitted to a peripheral device. Each set of SPI controller
can be configured as a master or a slave device.
6.14.2 Features
 Up to three sets of SPI controllers
 Supports Master or Slave mode operation
 Configurable bit length of a transaction word from 8 to 32-bit
 Provides separate 8-layer depth transmit and receive FIFO buffers
 Supports MSB first or LSB first transfer sequence
 Supports the Byte Reorder function
 Supports 3-wire, no slave select signal, bi-direction interface
