DELAY TO STABILIZE
During stop mode, the I bit in the condition code register (CCR) is
cleared to enable external interrupts. All other registers and memory
remain unaltered. All input/output (I/O) lines remain unchanged. The
processor can be brought out of stop mode only by an external interrupt
or reset.
