BAR_0 = H'00314156, BAMR_0 = H'00000000, BBR_0 = H'0094, BAR_1= H'00055555,

<Channel 0>
Address: H'00314156, Address mask: H'00000000
Bus cycle: I bus/instruction fetch/read (operand size is not included in the condition)
<Channel 1>
Address: H'00055555, Address mask: H'00000000
Data:
H'00000078, Data mask: H'0000000F
Bus cycle: I bus/data access/write/byte
On channel 0, the setting of I bus/instruction fetch is ignored.
On channel 1, a user break occurs when the DMAC writes byte data H'7x in address
H'00055555 on the I bus (write by the CPU does not generate a user break).
