What does the PCF85063 do if Month is set to 0x00?

[jamesbellinger]

We have a product in the field that accidentally sets Month to 0x00 when it should set it to 0x12. Given that Month should be from 0x01 to 0x12, what is the effect of this? Will it be the same as December of the previous year, or something else? Thanks!

Hello James,

In this case, you will have an undefined month (MONTHS = 00).

Once the DAY register is overflowed, it will change to January automatically (MONTHS = 01). After that, it will behave as expected.

I hope this helps.

Regards,

David
