CPU
When a break address is placed at the address of the instruction opcode, the instruction is not
executed until after completion of the break interrupt routine.
When a break address is placed at an address of an instruction operand, the instruction is executed
before the break interrupt.
When software writes a 1 to the BRKA bit, the break interrupt occurs just before the next instruction
is executed.
