Power Management
Interrupt
Slow Clock: SLCK
Bus Interface
The Real-time Clock is continuously clocked at 32768 Hz. The Power Management Controller
has no effect on RTC behavior.
RTC interrupt line is connected on one of the internal sources of the interrupt controller. RTC
interrupt requires the interrupt controller to be programmed first.
