19.2.2.2 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.
19.2.2.3 Break Auxiliary Register
The break auxiliary register (BRKAR) contains a bit that enables software to disable the COP while the
MCU is in a state of break interrupt with monitor mode.
BDCOP — Break Disable COP Bit
19.2.2.4 Break Status Register
The break status register (BSR) contains a flag to indicate that a break caused an exit from wait mode.
This register is only used in emulation mode.

This read/write bit disables the COP during a break interrupt. Reset clears the BDCOP bit.
1 = COP disabled during break interrupt
0 = COP enabled during break interrupt.
