Wait mode can also be exited by a reset or break. A break interrupt
during wait mode sets the SIM break stop/wait bit, SBSW, in the break
status register (BSR). If the COP disable bit, COPD, in the mask option
register is logic 0, then the computer operating properly module (COP)
is enabled and remains active in wait mode.
