MC68HC908SR12•MC68HC08SR12 — Rev. 5.0
Freescale Semiconductor
The STOP instruction:
After exiting stop mode, the CPU clock begins running after the oscillator
stabilization delay.
If a break module is present on the MCU, the CPU starts a break
interrupt by:
The break interrupt begins after completion of the CPU instruction in
progress. If the break address register match occurs on the last cycle of
a CPU instruction, the break interrupt begins immediately.
A return-from-interrupt instruction (RTI) in the break routine ends the
break interrupt and returns the MCU to normal operation if the break
interrupt has been deasserted.

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.
