6.12 Serial Peripheral Interface (SPI)
6.12.1 Overview
The Serial Peripheral Interface (SPI) applies to synchronous serial data communication and
allows full-duplex transfer. Devices communicate in Master/Slave mode with 4-wire bi-direction
interface. The NuMicro^TM M058S contains one set 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. SPI controller can be configured as a master or a slave device.
6.12.2 Features
 One set of SPI controllers
 Supports Master or Slave mode operation
 Configurable transfer bit length
 Provides transmit/receive can be transferred up to two times word transaction in one transfer
 Provides FIFO buffers
 Supports MSB or LSB first transfer
 Supports byte reorder function
 Supports byte or word suspend mode
 Supports Slave 3-wire mode
 SPI bus clock rate can be configured to equal the system clock rate
