Hi everyone,

 

So after looking at the RTC on the (K64 Sub-Family Reference Manual).  I find that RTC doesn't have time and date,

instead there is a 32-bit seconds counter with roll-over protection.  The RTC has a 1sec ISR, that I believe that it is

always going after it has been activated in software.  I some questions:

 

1.  What is "with roll-over protection"?

2.  Is it possible to write to the 32-bit second counter register?

3.  When a power down situation occurs is there a flag that is set to detect it?

4.  When power is restore is there a flag that is set to detect it?

 

Thank you.
