OIN — Output or Input Handshake Select Bit
PLS — Pulsed/Interlocked Handshake Operation Bit
EGA — Active Edge for Strobe A Bit
INVB — Invert Strobe B Bit
HNDS must be set to 1 for this bit to have meaning.
HNDS must be set to 1 for this bit to have meaning. When interlocked
handshake is selected, strobe B is active until the selected edge of
strobe A is detected.
0 = Input handshake
1 = Output handshake
0 = Interlocked handshake
1 = Pulsed handshake (Strobe B pulses high for two E-clock
0 = STRA falling edge selected, high level activates port C outputs
1 = STRA rising edge selected, low level activates port C outputs
0 = Active level is logic 0.
1 = Active level is logic 1.
