• Types
• Save address
• Exception code
• Remarks
 Word data accessed from addresses other than word boundaries (4n + 1, 4n + 3)

Instruction synchronous, processing-completion type
An address of the instruction following the instruction where a break occurs (a delayed branch
instruction destination address if an instruction is assigned to a delay slot)
H'5C0
An exception occurs when a DMA transfer is executed while an illegal instruction address
described above is specified in the DMAC. Since the DMA transfer is performed
asynchronously with the CPU instruction operation, an exception is also requested
asynchronously with the instruction execution. For details on DMAC, refer to section 13,
Direct Memory Access Controller (DMAC).
