A modulus-type baud rate generator provides rates from 64 baud to 524
Kbaud with a 16.78-MHz system clock.
Word length of either eight or nine bits is software selectable.
Optional parity generation and detection provide either even or odd
parity check capability.
Advanced error detection circuitry catches glitches of up to 1/16 of a bit
time in duration. Wakeup functions allow the CPU to run uninterrupted
until meaningful data is received.
