A.5.1.5 Stop Recovery
Out of STOP the controller can be woken up by an external interrupt. A clock quality check as after POR
is performed before releasing the clocks to the system. The fastest startup time possible is given by nuposc.
A.5.1.6 Pseudo Stop and Wait Recovery
The recovery from Pseudo STOP and Wait are essentially the same since the oscillator was not stopped in
both modes. In Pseudo Stop Mode the voltage regulator is switched to Reduced Performance Mode to
reduce power consumption. The returning out of pseudo stop to Full Perfomance takes tvup if the voltage
regulator is enabled.
The controller can be woken up by internal or external interrupts. After twrs in Wait or tvup+twrs in Pseudo
Stop the CPU starts fetching the interrupt vector.
