Question

When using the auto reset feature of the C8051F930's SmaRTClock, what should I set the match value to?

Answer

The alarm match value should be set to 2 less than the desired match value.  Version 1.4 of the datasheet incorrectly states that it should be 1 less than the desired match value. This will be corrected in the next version of the datasheet.
