aErr aDigital_ReadTmr(

aStemLib stemRef, const unsigned char module, const unsigned char nDigitalIndex, int* pTimerValue);

Parameters:

stemRef	-	An opaque library reference representing the aStem library which manages the communication with the BrainStem modules.
module	-	The IIC address of the module that will perform a timing measurement on one of its digital IO pins.  This need not be the router.
nDigitalIndex	-	The index of the timer input.
pTimerValue	-	Address of integer where the result will be stored.

Return Value:

This routine returns aErrNone when there are no errors.

Description:

This routine manages the BrainStem packets needed to request a digital pulse or transition timing measurement and receive the reply.  The result is a 2-byte value ranging from 0-65535 in units of 1.6usec.  The digital IO pin must be configured as a timer input prior to taking a reading.
