Enhanced Serial Communications Interface (ESCI) Module
13.1 Introduction
The enhanced serial communications interface (ESCI) module allows asynchronous communications
with peripheral devices and other microcontroller units (MCU).
The ESCI module shares its pins with general-purpose input/output (I/O) port pins. See
port location of these shared pins. The ESCI baud rate clock source is controlled by a bit (SCIBDSRC)
located in the configuration register.
