The use of a two stage cold and warm reset scheme on the device allows the implementation of NMIWD shadow registers. Shadow registers are reset only by power-on reset. These registers are used to store the NMIFLG information before reset assertion. This information can be used by the application software to provide additional information on the NMI status of the device before the last warm reset operation.
