Remarks
•
Before use, use function R_CGC_Set or R_CGC_Control to enable the sub-clock oscillator.
•
The sub-clock oscillator should be allowed to settle before starting the real-time clock.
Please refer to section 40.3.1 of the hardware manual for the settling time.
•
If the sub-clock oscillator is not running, this function will lock up.
•
The check for days in the month allows for leap years.
