High-speed Counter/Pulse Output Instructions Section 3-21
• To change the PV of the pulse output (origin fixed at 0).
• To stop pulse output.
This instruction is supported by CJ1M-CPU21/22/23 CPU Units only.

Operands P: Port Specifier
P specifies the port to which the operation applies.
C: Control Data
The function of INI(880) is determined by the control data, C.
NV: First Word with New PV
NV and NV+1 contain the new PV when changing the PV.
If C is 0002 hex (i.e., when changing a PV), NV and NV+1 contain the new PV.
Any values in NV and NV+1 are ignored when C is not 0002 hex.
