Serial Peripheral Interface (SPI) Module
16.1 Introduction
This section describes the serial peripheral interface (SPI) module, which allows full-duplex, synchronous,
serial communications with peripheral devices.
The text that follows describes the SPI. The SPI I/O pin names are SS (slave select), SPSCK (SPI serial
clock), MOSI (master out slave in), and MISO (master in/slave out). The SPI shares four I/O pins with four
parallel I/O ports.
16.2 Features
Features of the SPI module include:
16.3 Functional Description
The SPI module allows full-duplex, synchronous, serial communication between the MCU and peripheral
devices, including other MCUs. Software can poll the SPI status flags or SPI operation can be interrupt
driven.
If a port bit is configured for input, then an internal pullup device may be enabled for that port bit.
The following paragraphs describe the operation of the SPI module. Refer to
of the SPI I/O registers.
