Selects the break timing of the instruction fetch cycle
for channel A as before or after instruction execution.
0: PC break of channel A is set before instruction
1: PC break of channel A is set after instruction
Selects whether or not the data bus condition is
included in the break condition of channel A.
0: No data bus condition is included in the condition of

Selects the break timing of the instruction fetch cycle
for channel B as before or after instruction execution.
0: PC break of channel B is set before instruction
1: PC break of channel B is set after instruction
I Bus Cycle Condition Match Flag B
When the I bus cycle condition in the break conditions
set for channel B is satisfied, this flag is set to 1. In
order to clear this flag, write 0 into this bit.
0: The I bus cycle condition for channel B does not
1: The I bus cycle condition for channel B matches
