POWER SAVING MODE
(Cont’d)
3.4.3 Exit from WAIT and STOP Modes
The following paragraphs describe how the MCU
exits from WAIT and STOP modes, when an inter-
rupt occurs (not a Reset). It should be noted that
the restart sequence depends on the original state
of the MCU (normal, interrupt or non-maskable in-
terrupt mode) prior to entering WAIT or STOP
mode, as well as on the interrupt type.
Interrupts do not affect the oscillator selection.
3.4.3.1 Normal Mode
If the MCU was in the main routine when the WAIT
or STOP instruction was executed, exit from Stop
or Wait mode willoccur as soon as an interrupt oc-
curs; the related interrupt routine is executed and,
on completion, the instruction which follows the
STOP or WAIT instruction is then executed, pro-
viding no other interrupts are pending.
3.4.3.2 Non Maskable Interrupt Mode
If the STOP or WAIT instruction has been execut-
ed during execution of the non-maskable interrupt
routine, the MCU exits from the Stop or Wait mode
as soon as an interrupt occurs: the instruction
which follows the STOP or WAIT instruction is ex-
ecuted, and the MCU remains in non-maskable in-
terrupt mode, even if another interrupt has been
generated.
3.4.3.3 Normal Interrupt Mode
If the MCU was in interrupt mode before the STOP
or WAIT instruction was executed, it exits from
STOP or WAIT mode as soon as an interrupt oc-
curs. Nevertheless, two cases must be consid-
ered:
– If the interrupt is a normal one, the interrupt rou-
tine in which the WAIT or STOP mode was en-
tered will be completed, starting with the
execution of the instruction which follows the
STOP or the WAIT instruction, and the MCU is
still in the interrupt mode. At the end of this rou-
tine pending interrupts will be serviced in ac-
cordance with their priority.
– In the event of a non-maskable interrupt, the
non-maskable interrupt service routine is proc-
essed first, then theroutine in which theWAIT or
STOP mode was entered will be completed by
executing the instruction following the STOP or
WAIT instruction. The MCU remains in normal
interrupt mode.
Notes:
To achieve the lowest power consumption during
RUN or WAIT modes, the user program must take
care of:
– configuring unused I/Osas inputs without pull-up
(these should be externally tied to well defined
logic levels);
– placing all peripherals in their power down
modes before entering STOP mode;
When the hardware activated Watchdog is select-
ed, or when the software Watchdog is enabled,
the STOP instruction is disabled and a WAIT in-
struction will be executed in its place.
If all interrupt sources are disabled (GEN low), the
MCU can only be restarted by a Reset. Although
setting GEN low does not mask the NMI as an in-
terrupt, it will stop it generating a wake-up signal.
The WAIT and STOP instructions are not execut-
ed if an enabled interrupt request is pending.
