UCD90120A: Configuring GPI as Fault Commanding Input

Part Number:UCD90120A

I am currently working with the UCD90120A and have the following questions:

1. Can I configure a GPI to command a fault event? For example, can I toggle an input that will force the processor to store the current clock value to non-volatile memory.

2. Approximately how long will it take to write the information to FLASH memory?

3. How do I update the value of the Run Time Clock?

Thank you.
