General Digital I/O Function
⚫ Signal definition
Digital I/O functions involve input and output levels and pulse signals.The input
signal is the control signal provided externally to IT7800, the output signal is the
level signal provided externally by IT7800, and the pulse signal is the edge
signal switched between high and low levels.
Input signal

Typical: 5V
Range: 1.6V-15V
Current: ≤100mA
Low level signal
Typical: 0V
Range: -5V-0.8V
Current: ≤100mA
