Function
INI(880) can be used to execute the following operations
• To start or stop comparison of a high-speed counter's PV to the
comparison table registered with CTBL(882).
• To change the PV of the high-speed counter.
• To change the PV of the pulse output (origin fixed at 0).
• To stop pulse output.

1000 hex PWM(891) output 0
C: Control Data
0000 hex Starts comparison.
0001 hex Stops comparison.
0002 hex Changes the PV.
0003 hex Stops pulse output.
NV: First Word with New PV
If C is 0002 hex (i.e., when changing a PV), NV and NV+1 con-
tain the new PV. Any values in NV and NV+1 are ignored when
C is not 0002 hex.
