OK, my thought is

if panic is enabled : |--------WOR-------WS0--------WOR-------WS1 |------timeout------(panic)------timeout-----reset

I'm quite certainly missing something completely obvious here, but how can you get the WS1 interrupt *after* raising a panic? Aren't all interrupts disabled and the system fully halted once you get a panic(), especially when raised from an interrupt handler? If that's the case, how can the system continue to do things, such as receiving the WS1 interrupt and resetting ?

Again, I'm probably missing something obvious, but I'm interested to understand the reasoning here.

Thanks!
