Input signal from Pulse Generator. Input type is selected by FSW2. It
can be 1-phase or 2-phase input. Maximum 500kP/sec (z-phase
function is reserved). If the voltage exceeds 12V, it needs to use TP
type with connecting the external current limiting resistor(R). The
current should be within 5 to 15mA.
