15.2.2.1 Break Status and Control Register
The break status and control register (BRKSCR) contains break module enable and status bits.
BRKE — Break Enable Bit
BRKA — Break Active Bit
15.2.2.2 Break Address Registers
The break address registers (BRKH and BRKL) contain the high and low bytes of the desired breakpoint
address. Reset clears the break address registers.
142
This read/write bit enables breaks on break address register matches. Clear BRKE by writing a 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 1 to BRKA
generates a break interrupt. Clear BRKA by writing a 0 to it before exiting the break routine. Reset
clears the BRKA bit.
1 = Breaks enabled on 16-bit address match
0 = Breaks disabled
1 = Break address match
0 = No break address match
