Incremental mode
In this mode, the input pulse signal is counted, and the count value increases with the rising edge of each pulse
signal.
(2)
AB phase mode
In this mode, the high-speed count value is incremented or decremented according to two differential signals
(phase A and phase B). According to the frequency multiplication number, it can be divided into two modes:
double frequency and quadruple frequency, but its default counting mode is quadruple frequency mode.
