POR:
An illegal opcode reset has occurred since the last read of the RSR
1 = A POR has occurred
0 = Read of RSR
1 = An external reset has occurred since the last read of the RSR
0 = Read of RSR
1 = A COP reset has occurred since the last read of the RSR
0 = POR or read of RSR
0 = POR or read of RSR
1 = An illegal address reset has occurred since the last read of the
0 = POR or read of RSR
1 = Last reset caused by the USB module
0 = POR or read of RSR
1 = A LVI reset has occurred since the last read of PSR
0 = POR or read of RSR
