Figure 33 Stop Mode Entry Programming Sequence
Exiting Stop Mode
Stop Mode can be exited by active edge on the enabled wake-up pin(s) or by asserting the hard reset pin.
The wake-up circuitry will perform a sequence of predefined actions such as restore all supply voltages,
restore modules to operational mode including the oscillator and PLL. On stable clock per user configuration
is restored, peripheral clock gating, CPU clock gating is removed and the CPU starts to run from the instruction
following the one that sets the PD bit.
Note that if user has selected the PLL output as system clock (typical usage) but lock status of the PLL cannot
be achieved, the device cannot wake up and shall hang in this state until a device reset.
