Function
Sets the operation mode (Number of phases, Clear, Multiplier). Supports multi-processing.
Format
Ret = CntSetOperationMode ( Id , ChNo , Phase , Mul , SyncClr )
Parameters
Id

Initial Value
2-phase, 1x, Asynchronous clear
Remarks
Specifies the mode of specified channel. This function becomes valid when the counter stared.
"Synchronous clear" or "Asynchronous
clear" on SyncClr are followed Z-phase signal.
It isn't occurred Error even though calling CntSetOperationMode function
when you set CNT_ZPHASE_NOT_USE by CntSetZmode function.
The internal logic level of SyncClr is hold.
All held settings are reflected to the device when the counter is stared.
For example, the counter is started following the latest settings for Z-phase
by CntSetOperationMode function when you change from CNT_ZPHASE_NOT_USE
to CNT_ZPHASE_NEXT_ONE (or CNT_ZPHASE_EVERY_TIME) in the middle.
Example
Sets 1-phase, 1x, Asynchronous clear to the operation mode of channel 0.
