2. 2-Phase Input Mode
a) 2-phase, 1-multiplication operation mode: The counter counts A-phase
pulse input at the rising edge.
If A-phase input pulse precedes B-phase input pulse, up count operation starts at
−
the rising edge of A-phase pulse input.
If B-phase input pulse precedes A-phase input pulse, down count operation starts
−
at the falling edge of A-phase pulse input.
