The stand-alone SPI and I2C modules include many advanced features that are not present on the traditional MSSP module, which allows for core independent operation using the integrated hardware capabilities of each peripheral. Many devices also now come equipped with an advanced UART module that boasts several new features, and has integrated hardware that supports protocols such as DMX, LIN, and DALI. This document describes some of the features and modes of operation that can be found on these commonly used serial communication peripherals.
