The SoC contains a Motorola MC146818B-compatible real-time clock with 242 bytes of 
battery-backed RAM. The real-time clock performs twos key functions—keeping track of 
the time of day and storing system data, even when the system is powered down. The 
RTC operates on a 32.768 kHz crystal and a 3.3 V battery.

The RTC supports two lockable memory ranges. By setting bits in the configuration 
space, two 8-byte ranges can be locked to read and write accesses. This prevents 
unauthorized reading of passwords or other system security information.

The RTC supports a date alarm that allows for scheduling a wake up event up to 30 
days in advance.
