Note: When writing to RegCntA or RegCntB, the processor writes the counter comparison values. When reading
these locations, the processor reads back either the actual counter value or the last captured value if the capture
mode is active.
Note: When writing RegCntC or RegCntD, the processor writes the counter comparison values. When reading
these locations, the processor reads back the actual counter value.
