Reset:
BRKE — Break Enable Bit
BRKA — Break Active Bit
The break address registers (BRKH and BRKL) contain the high and low
bytes of the desired breakpoint address. Reset clears the break address
registers.

Write:
This read/write bit enables breaks on break address register matches.
Clear BRKE by writing a logic 0 to bit 7. Reset clears the BRKE bit.
This read/write status and control bit is set when a break address
match occurs. Writing a logic 1 to BRKA generates a break interrupt.
Clear BRKA by writing a logic 0 to it before exiting the break routine.
Reset clears the BRKA bit.

1 = Breaks enabled on 16-bit address match
0 = Breaks disabled on 16-bit address match
1 = When read, break address match
0 = When read, no break address match
