WD1984 transmitter equivalent, synchronous asynchronous receiver transmitter.
o TWO OPERATING MODES: SYNCHRONOUS & ASYN-
CHRONOUS
* 1 TO 8 CHARACTERS OF 5,6,7, OR 8 BITS PER CHARACTER TRANSMISSION
It SELECTABLE PARITY INSERTION IN OR AFTER LAST.
o DIAGNOSTIC LOCAL LOOP-BACK TEST MODE o DC TO 1M BITS/SEC (lx) OPERATION o TTL COMPATIBLE INPUTS AND OUTPUTS o SINGLE .
The WD1984 is a bus-oriented MOS/LSI device designed to provide two data communication protocols:
1. Asynchronous 2. Synchronous
The control registers are used to select the desired protocol and provide programmable format options within each protoco.
