[Description]
The number of input pulses is stored in a pulse input register. If bit 0 in CR0/CR28/CR56/CR84 is
turned ON, and the parameters are set correctly, the system will start the count. The number of
input pulses is neither prescaled nor averaged. The input pulses are count circularly. The number
of input pulses is in the range of -2147483648 to 2147483647.
