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. When interlocked
handshake is selected, strobe B is active until the selected edge of strobe A is
detected.
0 = Interlocked handshake
1 = Pulsed handshake (Strobe B pulses high for two E-clock cycles.)
0 = STRA falling edge selected, high level activates port C outputs (output
1 = STRA rising edge selected, low level activates port C outputs (output
0 = Active level is logic 0.
1 = Active level is logic 1.
