CFG_CntrCompareData gets or sets the counters' compare data of the device.
This data is used for comparing with the counter's count value.
In the property CFG_CntrIndicatorControl,
four types of indicators are provided: OVERCOMPLEVEL, OVERCOMPPULSE,
UNDERCOMPLEVEL, UNDERCOMPPULSE. When the Indicator is set to OVERCOMPLEVEL/OVERCOMPPULSE,
when the counter's count value exceeds the compare data, the indicator will
indicate over compare state (level or pulse) ; When the Indicator is set to
UNDERCOMPLEVEL/OVERCOMPPULSE, when the counter's count value below the compare
data, the indicator will be on an under compare state (level or pulse).
