7.Q&A
7.6 How do I recover from stop mode?
The following events end stop mode:
• The following four interrupts change the device to the oscillation stabilization wait state.
• External level-detect interrupt or edge-detect interrupt.
• Oscillation stabilization wait timer for the main clock when oscillation not halted.
• Sub oscillation stabilisation timer when oscillation not halted.
• Real time clock when oscillation not halted.
If using interrupt processing, remember to set the I flag (I), interrupt level mask register (ILM), and interrupt
control register (ICR).
• Input to the INIT pin invokes an initialization reset (INIT) followed by an oscillation stabilization delay and
then an operation reset (RST).
In the case of an INIT pin input, an oscillation stabilization wait is required, depending on the width of the
INIT pin input.
