The
Asynchronous
module is a serial I/O communications peripheral. It
contains all the clock generators, shift registers and
data buffers necessary to perform an input or output
serial data transfer independent of device program
execution. The AUSART, also known as a Serial
Communications Interface (SCI), can be configured as
a full-duplex asynchronous system or half-duplex
synchronous system. Full-Duplex mode is useful for
communications with peripheral systems, such as CRT
terminals
Synchronous mode is intended for communications
with peripheral devices, such as A/D or D/A integrated
circuits, serial EEPROMs or other microcontrollers.
These devices typically do not have internal clocks for
baud rate generation and require the external clock
signal provided by a master synchronous device.
