Serial communications interface (SCI)
Introduction
The serial communications interface (SCI) offers a flexible means of full-duplex data
exchange with external equipment requiring an industry standard NRZ asynchronous serial
data format. The SCI offers a very wide range of baud rates using two baud rate generator
systems.
