2. The execution address of the illegal instruction when an illegal op code exception occurs is calculated
with (Restored PC – 4).

: The value of the PC saved to EIPC or FEPC when interrupt/exception processing
is started. However, the value of the PC saved when an interrupt is granted during
the DIVH (division) instruction execution is the value of the PC of the current
instruction (DIVH).
