ASYNCHRONOUS SERIAL COMMUNICATIONS INTERFACE (SCI-A)
10.6 ASYNCHRONOUS SERIAL COMMUNICATIONS INTERFACE (SCI-A)
10.6.1 Introduction
The Asynchronous Serial Communications Inter-
face (SCI-A) offers a flexible means of full-duplex
data exchange with external equipment requiring
an industry standard NRZ asynchronous serial
data format. The SCI-A offers a very wide range of
baud rates using two baud rate generator sys-
tems.

10.6.3 General Description
The interface is externally connected to another
device by two pins (see
Through these pins, serial data is transmitted and
received as frames comprising:
