5.7.3
The illegal instructions are general illegal instructions and slot illegal instructions. The exception
handling by the general illegal instruction starts when an undefined code is executed. The
exception handling by the slot illegal instruction starts when a particular instruction (e.g. its code
length is two words or more, or it changes the PC contents) at a delay slot (immediately after a
delayed branch instruction) is executed. The exception handling by the general illegal instruction
and slot illegal instruction is always executable in the program execution state.
The exception handling is as follows:
1. The contents of PC, CCR, and EXR are saved in the stack.
2. The interrupt mask bit is updated and the T bit is cleared to 0.
3. An exception handling vector table address corresponding to the occurred exception is
Table 5.10 shows the state of CCR and EXR after execution of illegal instruction exception
handling.

generated, the start address of the exception service routine is loaded from the vector table to
PC, and program execution starts from that address.
