Any input used to select an internal PSD935G2 function.
In multiplexed mode, latched addresses generated from ADIO delay to address output on any Port.
WR timing has the same timing as E, DS signals.
tWHAX2 is Address Hold Time for DPLD inputs that are used to generate chip selects for internal PSD memory.
