BRCR sets the following conditions:
1. Channels A and B are used in two independent channel conditions or under the sequential
2. A break is set before or after instruction execution.
3. Specify whether to include the number of execution times on channel B in comparison
4. Determine whether to include data bus on channel B in comparison conditions.
5. Enable PC trace.
BRCR is a 32-bit readable/writable register that has break conditions match flags and bits for
setting a variety of break conditions.
