information applies. The CMDREG1B or CMDREG3B fields of the state frame are modified as
appropriate to encode the unimplemented instruction opcode. It is the user exception handler’s
responsibility to use the E3 and E1 field encodings to recognize which state frame information
applies. When E3 = 1 and E1 = 1, E3 takes priority and the state frame information for E3 = 1
must be used.
