Serial Peirpheral Interface (SPI)
17.1 Introduction
This section describes the serial peripheral interface (SPI) module, which allows full-duplex, synchronous,
serial communications with peripheral devices.
17.2 Features
Features of the SPI module include:
17.3 Pin Name and Register Name Conventions
The generic names of the SPI input/output (I/O) pins are:
The SPI shares four I/O pins with a parallel I/O port. The full name of an SPI pin reflects the name of the
shared port pin.
