Can the WDT be routed to a GPIO pin

[username]

As most of us know when you starve the CPU core your going to get a WDT warning in the terminal.
I am curious if there is some kind of ISR hook or other call that can be implemented in code so that if it gets triggered I can toggle a GPIO pin.

Task wdt has weak handler and yes, you can do this.

esp_task_wdt_isr_user_handler()
