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 ?
Typically, WS1 is not an interrupt. Instead, it's a hard system-level reset.
Ah, right, true. I missed that aspect because on my HW, triggering a system-level reset on WS1 is optional. I can actually get an interrupt on both WS0 and WS1, and no reset at all.
But a normal configuration indeed involves having the WS1 event configured in HW to be a system-level reset.
So, OK, it makes sense. Thanks for the clarification!
