BRCRH
BRCRL
The break control register (BRCR) is used to make the following settings:
1. Setting of independent channel mode or sequential condition mode for channels A, B, C, and D
4. Selection of pre- or post-instruction-execution break in case of an instruction fetch cycle
3. Selection of whether the data bus is to be included in the comparison conditions for channels C
4. Selection of whether an execution-times break is to be set for channels C and D
5. Selection of whether a PC trace is to be executed
BRCR also contains flags that are set when a condition is satisfied. BRCR is initialized to
H'00000000 by a power-on reset; after a manual reset, its value is undefined.
