MSPM0G3507: Reconfigure WWDT Periods

Part Number: MSPM0G3507

Tool/software:

Hello

I had set the watchdog's (WWDT0) period to 2 seconds when the device (MSPM0G3507) is in Run state . Is it possible for WWDT0 to be reconfigured to 64 seconds when the device (MSPM0G3507) enters sleep mode?

If possible, how to do it? Thanks.

Best Regards,

Andy

    Hi Andy,

    seen from TRM, you can not reconfigure WWDT0 in code.

    For workaround, you can enable WWDT0 and WWDT1 at the same time(For example configure WWDT0 stop while in low power mode), and feed them in the run mode, and only feed WWDT1 in the low power mode.
