16.4 Break Module Registers
These registers control and monitor operation of the break module:
16.4.1 Break Status and Control Register (BRKSCR)
The break status and control register contains break module enable and status bits.
BRKE — Break Enable Bit
BRKA — Break Active Bit
16.4.2 Break Address Registers
The break address registers contain the high and low bytes of the desired breakpoint address. Reset
clears the break address registers.

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.
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 = Breaks enabled on 16-bit address match
0 = Breaks disabled
1 = Break address match
0 = No break address match
Break status and control register (BRKSCR)
Break address register high (BRKH)
Break address register low (BRKL)
Break status register (BSR)
Break flag control register (BFCR)
