Data:
Bus cycle: Y bus/data access/write/word
On channel A, a user break occurs during word read from address H'01000000 in the
memory space. On channel B, a user break occurs when word data H'4567 is written in
address H'0000F000 in the Y memory space. The X/Y-memory space is changed by a
mode setting.
Address: H'00314156, Address mask: H'00000000
Bus cycle: I bus/instruction fetch/read (operand size is not included in the condition)
Address: H'00055555, Address mask: H'00000000
Data:
Bus cycle: I bus/data access/write/byte
On channel A, a user break occurs when instruction fetch is performed for address
H'00314156 in the memory space.
On channel B, a user break occurs when the I bus writes byte data H'7 in address
H'00055555.
