General Digital I/O Function
⚫
Digital I/O functions involve input and output levels and pulse signals.The input
signal is the control signal provided externally to IT7900, the output signal is the
level signal provided externally by IT7900, and the pulse signal is the edge
signal switched between high and low levels.
