HIB#18

Can get two matches per day in calendar mode

Description

When the CAL24 bit in the Hibernation Calendar Control (HIBCALCTL) register is clear, the RTC counts in 12 hour, AM/PM mode. The AM/PM bit in the Hibernation Calendar Match 0 (HIBCALM0) specifies whether the match should occur in the AM or the PM. However, this bit is ignored when determining if a match is occurring. As a result, an RTC match could occur twice in one day.

Workaround

Adjust the match time to 24 hour mode before configuring the HIBCALM0 register and set the CAL24 bit. Alternatively, when the match occurs, check the AM/PM bit in the Hibernation Calendar (HICAL0) register to determine if the match is correct.
