2. 16-bit instruction code that is not assigned as instructions is handled as an ordinary
3. An ordinary illegal instruction or branched instruction (i.e., an illegal slot instruction)
4. The delayed branch actual occurs after the slot instruction is executed. Except for

illegal instruction and produces illegal instruction exception processing.
Example: H'FFFF [ordinary illegal instruction]
that follows a BRA, BT/S or another delayed branch instruction will cause illegal
instruction exception processing.
Example 1:

Example 2:

branches such as register updates, however, delayed branch instructions are executed
before delayed slot instructions. For example, even when the contents of a register that
stores a branch destination address in a delay slot are changed, the branch destination
remains the register contents prior to the change.
renew the SR, RS or RE register (SETRC, LDRS, etc.) in the last three instructions of a
repeat program (loop) with three or less instructions or a program (loop) with four or
more instructions, illegal instruction exception processing is started. Refer to section
4.18, DSP Repeat (Loop) Control, for more information.
