(1) On a write, the maximum value for “day” depends on the values written to “month” and the “year”.
(2) The data and time default values are set if one of the following three conditions occur:
- When the device is first powered-up at the factory
- A device power-up following the depletion of the real-time clock power source
- In the event of an abnormal condition which may cause the real-time clock to contain values which are not in the valid range
The date and time are not set to the default values when “Restore Factory Defaults” is performed via the Display Module or communications port.
