6.13 Serial Peripheral Interface (SPI)

6.13.1 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

® NUC029LDE/NUC029SDE 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. This SPI controller can be

configured as a master or a slave device.

The SPI controller supports the variable bus clock function for special applications.
