USB watchdog using SOF ISR and Timer
Hi All ,
I want to implement a WDT functionality for USB using SOF ISR . I need to start and stop SOF monitoring during some conditions .
What I thought of using a timer and resetting the timer in SOF ISR , If timer is not getting reset , I am hoping to get a timer interrupt . I don't want to call any API s from ISR . I saw one reset Pin in the top design , is it possible to make use of that ?
What I an expecting is a signal kind of hardware connection to timer reset , that can be set from ISR easily . Is it possible ? or there is any better way ?
