TMS320F28384D: Watchdog Reset and Watchdog Interrupt Mode

Part Number: TMS320F28384D

Hi champs,

In TRM, we say to avoid unexpected behavior, software should not change the configuration of the watchdog while WDINT is active. For example, changing from interrupt mode to reset mode while WDINT is active will immediately reset the device.

Here is the question, my customer enables watchdog interrupt mode, wants to handle necessary procedures in ISR before reset the device. Based on the watchdog description in TRM, he wants to know when finishing the needed procedures in ISR, is it the right way changing watchdog from interrupt mode to reset mode in ISR and then reset the device? Or do we have any other recommend method to reset device in this situation?

Regards,

Luke
