Long title, but basically sums it up - is there any way to put the nRF51 into the off state from within the hard-fault handler if the soft-device was enabled prior to the fault? The complication is that the soft-device seems to protect the NRF_POWER peripheral, and when you're inside the hard-fault handler, you can't use sd_power_system_off() nor can you just access NRF_POWER->SYSTEMOFF. So it seems I'm somewhat stuck.
Any ideas on how I might be able to get around this?
The goal is to put the system into the off state to disable the WDT, in case it was running - I don't want the actual WDT reset to occur since technically, it's not guaranteed to preserve RAM through the reset (many of the other reset sources preserve RAM, but for whatever reason, the WDT does not). I've observed that RAM is usually preserved, but since it's not in the datasheet, I don't want to rely on it.
Thanks!
