GENERAL DESCRIPTION

The COM81C17 TPUART is an asynchronous

only

receiver/transmitter

with

a

built

in

programmable baud rate generator housed in a

twenty pin package.

The TPUART receives

serial data streams and converts them into

parallel data characters for the processor. While

receiving serial data, the TPUART will also

accept data characters from the processor in

parallel format and convert them into serial

format along with start, stop and optional parity

bus. The TPUART will signal the processor via

interrupt when it has completely transmitted or

received a character and requires service.

Complete status information is available to the

processor through the status register.

The

TPUART features two general purpose control

pins that can be individually programmed to

perform

as

terminal

or

modem

control

handshake signals.
