Bus hold, branch instruction fetch, successive instruction fetch, operand data access, and DMA transfer are
Bus hold has the highest priority, followed by DMA transfer, operand data access, branch instruction fetch, and
However, an instruction fetch may be inserted between the read access and write access in a read-modify-write
If an instruction is executed for two or more accesses, an instruction fetch and bus hold are not inserted between
