Serial Communications Interface (SCI)
16.1 Introduction
The SCI allows asynchronous communications with peripheral devices and other MCUs.
16.2 Features
The SCI module’s features include:
16.3 Pin Name Conventions
The generic names of the SCI input/output (I/O) pins are:
SCI I/O lines are implemented by sharing parallel I/O port pins. The full name of an SCI input or output
reflects the name of the shared port pin.
SCI I/O pins.The generic pin names appear in the text of this section.
