BRCR sets the following conditions:
1. Channels A and B are used in two independent channels condition or under the sequential
condition.
2. A break is set before or after instruction execution.
3. A break is set by the number of execution times.
4. Determine whether to include data bus on channel B in comparison conditions.
5. Enable PC trace.
6. Enable the ASID check.
The break control register (BRCR) is a 32-bit read/write register that has break conditions match
flags and bits for setting a variety of break conditions. A power-on reset initializes BRCR to
H'00000000.
