The CPU was reset due to the supply voltage being lower than the 3.3V Supply Monitor (BOD33) threshold level.
The CPU was reset by the AWIRE
The CPU was reset because the RES strobe in the OCD Development Control register has been written to one.
The CPU was reset because had detected an illegal access.
The chip was reset by the JTAG system reset.
The CPU was reset because of a watchdog time-out.
The CPU was reset due to the RESET pin being asserted.
The CPU was reset due to the core supply voltage being lower than the brown-out threshold level.
The CPU was reset due to the core supply voltage being lower than the power-on threshold level, or due to the input voltage
being lower than the minimum required input voltage for the voltage regulator.
