**W860551/P UART with FIFO and Printer Port Controller             <94
***Info:...
***Versions:...
***Features:
o  Easily interfaces with most popular microprocessors
o  Pin compatible and functionally compatible with the existing 
   W860451
o  Centronics parallel interface
o  Capable of running all existing 16450 and 16550 software
o  Uses system's 14.3181 BMHz clock input
o  In FIFO mode transmitter and receiver are each buffered with 
   16-byte FIFOs to reduce number of intercepts presented to the CPU
o  Adds or deletes standard asynchronous communication bits (start, 
   stop, and parity) to or from serial data
o  Independently controlled transmit, receive, line status, and data 
   set interrupts
o  Programmable baud rate generator
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
   - Baud generation
o  False start bit detection
o  Internal diagnostic capabilities:
   - Loopback controls for communications link fault isolation
   - Break, parity, overrun, framing error simulation
o  Fully prioritized interrupt system controls
o  40-pin PDIP package for W860551 and 44-pin PLCC package for 
   W86C551P
