MOTOROLA
If enabled, the break module is active in wait mode. In the break routine,
the user can subtract one from the return address on the stack if the BW
bit in the break status register is set.
The break module is inactive in stop mode. A break interrupt causes exit
from stop mode and sets the BW bit in the break status register. The
STOP instruction does not affect break module register states.
The WAIT instruction:
The STOP instruction:
After exiting stop mode, the CPU clock begins running after the oscillator
stabilization delay.

Clears the interrupt mask (I bit) in the condition code register,
enabling interrupts. After exit from wait mode by interrupt, the I bit
remains clear. After exit by reset, the I bit is set.
Disables the CPU clock
Clears the interrupt mask (I bit) in the condition code register,
enabling external interrupts. After exit from stop mode by external
interrupt, the I bit remains clear. After exit by reset, the I bit is set.
