BRKA — Break Active Bit
The break address registers contain the high and low bytes of the
desired breakpoint address. Reset clears the break address registers.
The break status register (BSR) contains a flag to indicate that a break
caused an exit from stop or wait mode. This status bit is useful in
applications requiring a return to wait or stop mode after exiting from a
break interrupt.

Write:
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.
