Break Module (BRK)
BRKE — Break Enable Bit
BRKA — Break Active Bit
18.5.2 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.
18.5.3 SIM Break Status Register
The SIM break status register (SBSR) contains a flag to indicate that a break caused an exit from wait
mode. This register is used only in emulation mode.
208
This read/write bit enables breaks on break address register matches. Clear BRKE by writing a logic
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 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.
1 = Breaks enabled on 16-bit address match
0 = Breaks disabled on 16-bit address match
1 = (When read) Break address match
0 = (When read) No break address match
Note: Writing a logic 0 clears SBSW.
