Enhanced Serial Communications Interface (ESCI) Module
14.1 Introduction
The enhanced serial communications interface (ESCI) module allows asynchronous communications
with peripheral devices and other microcontroller units (MCU).
14.2 Features
Features include:
14.3 Pin Name Conventions
The generic names of the ESCI input/output (I/O) pins are:
ESCI I/O lines are implemented by sharing parallel I/O port pins. The full name of an ESCI input or output
reflects the name of the shared port pin.
ESCI I/O pins. The generic pin names appear in the text of this section.
