Register 18: Hibernation Calendar Match 0 (HIBCALM0), offset 0x330
The Hibernation Calendar Match 0 (HIBCALM0) register is used when the CALEN bit is set in the
HIBCALCTL register. This register is loaded with desired match values for calendar mode. Once
the HIBCAL0/1 register values equal the HIBCALM0/1 register values, the RTCALT0 bit is set in
the HIBRIS register.
Note: The day of week, month and year are not included in the match functionality.
