peripheral control register. The general sequence for clearing an interrupt is based on an
access to the status register followed by a read or write to an associated register.
The clearing sequence resets the internal latch. A pending interrupt (that is, waiting to be
serviced) is therefore lost if the clear sequence is executed.
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
present while exiting 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 process shown in
Figure
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.
