Hibernation Module
trim register is applied to the predivider to allow fine-tuning of the RTC rate, in order to make
corrections to the rate. The software application can make adjustments to the predivider trim
register to account for variations in the accuracy of the input time source. The nominal value is
0x7FFF, and it can be adjusted up or down in order to fine-tune the RTC rate.
Returns:
None.
