The RTC registers are placed in the AON domain and are clocked using 2 MHz MF clock. All configuration and status registers are preserved in all power modes except for SHUTDOWN. The MCU domain contains an interface to the AON_RTC registers to ensure fast access with minimum latency on the system bus. Due to synchronization between the MCU interface and the AON domain, there is a delay in the system that software must take into account.
