The RTC also 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

The RTC also supports a data alarm that allows for scheduling a wakeup event up to 30 days in
advance, rather than just 24 hours in advance.
