[Description]
If bit 0 in CR0/CR28/CR56/CR84 is turned from OFF to ON, the number of pulses received by the
input terminals will be read according to the cycle set. The setting of a cycle is shown below.

Cycle of reading the number of pulses
If the setting value is larger than 1000, the cycle will be counted as 1000 milliseconds. If the setting
value is less than 1, the cycle will be counted as 1 millisecond.
