Parallel Data Input. Data is clocked into the Transmitter on the rising edge of CKW if ENA is LOW
(or on the next rising CKW with ENN LOW). If ENA and ENN are HIGH, a Null character (K28.5) is
sent. When MODE is HIGH, D
Special Character/Data Select. A HIGH on SC/D when CKW rises causes the transmitter to encode
the pattern on D

Send Violation Symbol. If SVS is HIGH when CKW rises, a Violation symbol is encoded and sent
while the data on the parallel inputs is ignored. If SVS is LOW, the state of D

Enable Parallel Data. If ENA is LOW on the rising edge of CKW, the data is loaded, encoded, and
sent. If ENA and ENN are HIGH, the data inputs are ignored and the Transmitter will insert a Null
character (K28.5) to fill the space between user data. ENA may be held HIGH/LOW continuously or
it may be pulsed with each data byte to be sent. If ENA is being used for data control, ENN will normally
be strapped HIGH, but can be used for BIST function control.
