(1) CPU access to other than BIU on DMAC read side is possible
(2) CPU access to other than BIU on DMAC write side is possible
(3) CPU access to other than BIU on DMAC read/write side is possible
(4) CPU access to other than BIU on DMAC read side is possible
(5) CPU access to other than BIU on DMAC read/write side is possible
(6) CPU access to other than BIU on DMAC write side is possible
However, when a DMA access to external address space followed by CPU access to external address
space is occurred, CPU access next to DMA cycle may not be occurred.
