Figure 17-3. Break Status and Control Register (BRKSCR)
BRKE — Break Enable Bit
This read/write bit enables breaks on break address register matches.
Clear BRKE by writing a logic zero to bit 7. Reset clears the BRKE bit.
1 = Breaks enabled on 16-bit address match
0 = Breaks disabled
BRKA — Break Active Bit
This read/write status and control bit is set when a break address
match occurs. Writing a logic one to BRKA generates a break
interrupt. Clear BRKA by writing a logic zero to it before exiting the
break routine. Reset clears the BRKA bit.
1 = Break address match
0 = No break address match
