General
Description
The
a8251
MegaCore function provides an interface between a
microprocessor and a serial communications channel. The
a8251
receives
and transmits data in a variety of configurations including 7- or 8-bit data
words, with odd, even, or no parity, and 1 or 2 stop bits. The transmitter
and receiver can be designed for synchronous or asynchronous operation.
