**UM82C852     Multi I/O For XT                                    <91
***Info:
The  Multi-I/O  chip, UM82C852  is  an  integrated  chip of  UM82C450,
UM82C11, UM82C8167. This  chip is a Multi-I/O for  PC/XT and PS2 model
30.

The   82C450  asynchronous   communications  element   (ACE)  performs
serial-to-parallel  conversion   on  data  characters   received  from
peripheral  devices or  modems, and  parallel-to-serial  conversion of
data characters transmitted by the CPU. The complete status of the ACE
can  be read  at  any time  during  functional operation  by CPU.  The
information obtained  includes the type and condition  of the transfer
operations being performed and error conditions.

The  82C11  parallel  port  provides  the user  with  a  bidirectional
parallel data  port that fully  supports the parallel  Centronics type
printer.

The 82C8167 real time clock includes an addressable real time counter,
56 bits  of static RAM with  an on chip oscillation  circuit which can
generate the 32,768 Hz time base.

The 82C852 is packaged in a 68-pin plastic leaded chip carrier.

**W86C452   I/O controller for IBM PC/AT                         Jul89
***Info:...
***Versions:...
***Features:
o  Easily interfaces to most popular microprocessors.
o  Dual-channel version of W86C450
o  Centronics printer interface
o  Independently controlled transmit, receive, line status, and data 
   set interrupts.
o  Programmable baud generator allows division of any input clock 
   by l to (2^16 -l) and generates the internal 16 x clock.
o  Independent receiver clock input.
o  MODEM control functions (CTS, RTS, DSR, DTR. RI. and DCD).
o  Fully programmable serial-interface characteristics:
   - 5, 6, 7. or 8-bit characters
   - Even, odd. or no-parity bit generation and detection
   - 1, 1.5 or 2-stop bit generation
o  False start bit detection.
o  TRl-STATE TTL drive capabilities for bidirectional data bus and 
   control bus on each channel
o  Internal diagnostic capabilities:
   - Loopback controls for communications link fault isolation
   - Break, parity, overrun, framing error simulation.
o  Fully prioritized interrupt system controls.
