DESCRIPTION
The TL16C2552 is a dual universal asynchronous
receiver and transmitter (UART). It incorporates the
functionality of two TL16C550D UARTs, each UART
having its own register set and FIFOs. The two
UARTs share only the data bus interface and clock
source,
otherwise
they
Another
name
for
the
Asynchronous Communications Element (ACE), and
these terms will be used interchangeably. The bulk
of this document describes the behavior of each
ACE, with the understanding that two such devices
are incorporated into the TL16C2552.
