TMS320F28P650DK: CPU2 watchdog reset

Tool/software:

Hi,

I'm working with the TMS320F28P650DK and I have a few questions regarding the watchdog reset behavior and CPU2 boot sequence after watchdog reset:

1. What exactly happens when CPU2's watchdog expires?

2. How does CPU2 reboot after a watchdog reset?

3. What role does CPU1 play in booting CPU2 after such a reset?

4. Are there any configuration steps required in CPU1 to allow CPU2 to boot correctly after a watchdog-triggered reset?

Any clarification or pointers to relevant documentation would be appreciated.

Thanks!
