Syntax

DioGetCounterOverflowMode (nMasterHandle, pnOverflowMode, pnStatus)

Parameters

Name	Type	Comments

pnOverflowMode	PSHORT	Program counter over flow modes are: 0 Overflow disabled. 1 Overflow enabled.
pnStatus	PSHORT	Returned status: 0 on success, negative number on failure.

Comments

If the overflow mode is enabled, then the sequencer will not stop at the last step, but instead wrap around to step zero. If the overflow mode is disabled, then the sequencer will go to HALT state at the last step of the memory.

Example

The following example enables the counter to over flow mode and returns the overflow mode setting:

SHORT nStatus, nOverflowMode;

DioSetupCounterOverflowMode (nMasterHandle, 1, &nStatus);

DioGetCounterOverflowMode (nMasterHandle, &nMode, &nStatus);
