Note that the main loop of the application should be responsible for requesting the
sleep manager to put the device to sleep, as shown in Figure 4-1.

SLEEPMGR_Sleep()
Main loop
If an interrupt occurs while the sleep manager is about to put the device to sleep, it
will instantly wake up again and execute the corresponding ISR. Any update of the
locks must then occur in the ISR to ensure that the locks are set before the sleep
manager is requested to put the device to sleep again. A general example of an ISR
is shown in Figure 4-2.
Note that the sleep modes must also be unlocked when the firmware module is either
done with its task or it locks a different sleep mode.
