10.2.1 Termination by interrupt request occurrence
When terminating Stop mode by interrupt request occurrence, instructions are executed after a certain time
measured by the watchdog timer has passed.
Table 10.2.2 lists the interrupts used to terminate Stop mode.
Before executing the STP instruction, enable interrupts used to terminate Stop mode.
In addition, the interrupt priority level of the interrupt used to terminate Stop mode must be higher than the
processor interrupt priority level (IPL) of the routine where the STP instruction is executed. When multiple
interrupts in Table 10.2.2 are enabled, Stop mode is terminated by the first interrupt request.
There is possibility that all interrupt requests occur after the oscillation starts in
and
(Note) after the watchdog timer’s MSB becomes “0.”
For interrupts not to be accepted, set their interrupt priority levels to level 0 (interrupt disabled) before
executing the STP instruction.
Note : The interrupt request which has the highest priority is accepted first.
