Can the device reset without going through NVIC_SystemReset()?

[abhipray]

Some situations like heavy ble activity causes the nrf52832 to restart without hitting breakpoints in the NVIC_SystemReset.

Assuming there aren't any hardware issues, is it possible for a device soft-reset without going through the core_cm4.h NVIC_SystemReset call?

Yes, and you can look at the reset registor.

uint32_t reset_reason;
sd_power_reset_reason_get(&reset_reason);
