P: Port Specifier
P specifies the port to which the operation applies.
P
0000 hex Pulse output 0
0001 hex Pulse output 1
0010 hex High-speed counter 0
0011 hex High-speed counter 1
0100 hex Interrupt input 0 in counter mode
0101 hex Interrupt input 1 in counter mode
0102 hex Interrupt input 2 in counter mode
0103 hex Interrupt input 3 in counter mode
1000 hex PWM(891) output 0
1001 hex PWM(891) output 1
C: Control Data
The function of INI(880) is determined by the control data, C.
C
0000 hex Starts comparison.
0001 hex Stops comparison.
0002 hex Changes the PV.
0003 hex Stops pulse output.
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.
