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