Maintains a one-second count, unique over a period of thousand of years
32-bit RTC counter can be initialized by software to specific initial count value
Provides an alarm function with programmable and maskable alarm interrupt
Provides programmable and maskable every second interrupt
Uses two possible clock sources: the CSB bus clock or an external RTC clock
RTC function can be disabled if needed
RTC enable/disable mode
