INTERRUPTS (Cont’d)
7.3 INTERRUPTS AND LOW POWER MODES
All interrupts allow the processor to exit the WAIT
low power mode. On the contrary, only external
and other specified interrupts allow the processor
to exit from the HALT modes (see column “Exit
from HALT” in “Interrupt Mapping” table). When
several pending interrupts are present while exit-
ing HALT mode, the first one serviced can only be
an interrupt with exit from HALT mode capability
and it is selected through the same decision proc-
ess shown in
Note: If an interrupt, that is not able to Exit from
HALT mode, is pending with the highest priority
when exiting HALT mode, this interrupt is serviced
after the first one serviced.

7.4 CONCURRENT & NESTED MANAGEMENT
The following
different interrupt management modes. The first is
called concurrent mode and does not allow an in-
terrupt to be interrupted, unlike the nested mode in
Figure
in this order from the lowest to the highest: MAIN,
IT4, IT3, IT2, IT1, IT0, TLI. The software priority is
given for each interrupt.
Warning: A stack overflow may occur without no-
tifying the software of the failure.
