The CPU was reset due to the supply voltage 3V3 being lower than the brown-out threshold level.
The CPU was reset because the RES strobe in the OCD Development Control register has been written to one.
The CPU was reset because it had detected an illegal access.
The CPU was reset by setting the bit RC_CPU in the JTAG reset register.
The CPU was reset because of a watchdog timeout.
The CPU was reset due to the RESET pin being asserted.
The CPU was reset due to the supply voltage 1V8 being lower than the brown-out threshold level.
The CPU was reset due to the supply voltage being lower than the power-on threshold level.
