5.4 Single Phase Speed Counter
This function counts the number of changes of the count input from OFF to ON during the every specified sampling
time. The count value in a sampling time is stored in the hold value register. This counter operation is enabled while
the soft-gate is ON. When the soft-gate is OFF, the hold value is cleared to 0. The setting range of the sampling time
is 1 to 1000 ms (1 ms units). The count value range is H0000 0000 to HFFFF FFFF (32-bit).
The function selection is done through configuration register1.
