15.4 Break Module Registers
These registers control and monitor operation of the break module:
15.4.1 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

This read/write bit enables breaks on break address register matches. Clear BRKE by writing a 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 one to BRKA
generates a break interrupt. Clear BRKA by writing a 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
