Specified conditions: Channel A/channel B independent mode
<Channel A>
Address:
Data:
Bus cycle: I bus (CPU cycle)/instruction fetch/read (operand size is not included in the
condition)
<Channel B>
Address:
Data:
Bus cycle: I bus (CPU cycle)/data access/write/byte
On channel A, a user break occurs when instruction fetch is performed for address H'00314156
in the external memory space.
On channel B, a user break occurs when byte data H'7x is written in address H'00055555 in the
external memory space by the CPU.
