Emerson MITX-440-DVI-2E, MITX-430 manual Functional Description

Functional Description

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 reading of passwords or other system security information.

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.
