Function description
There are three kinds of output control signals: the single control pulse (SP), after the 12-bit receiving pulse is correct, the corresponding output port will produce a positive pulse with the pulse width of 107ms. if you maintain the control pulse (HP), when you press the continuous button, the output pulse width is equal to the press time. The HP signals can be synchronously parallel produced because the continuous key has the multi-key operation function, when it receives the continuous signal, the high level is produced by the corresponding output port.
