A.6.1.2
Provided an appropriate external reset signal is applied to the MCU, preventing the CPU from executing
code when V
the PORF bit in the CRG flags register has not been set.
A.6.1.3
When external reset is asserted for a time greater than PW
reset, and the CPU starts fetching the reset vector without doing a clock quality check, if there was an
oscillation before reset.
A.6.1.4
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.
If the MCU is woken-up by an interrupt and the fast wake-up feature is enabled (FSTWKP = 1 and
SCME = 1), the system will resume operation in self-clock mode after t
A.6.1.5
The recovery from pseudo stop and wait is essentially the same since the oscillator is not stopped in both
modes. The controller can be woken up by internal or external interrupts. After t
the interrupt vector.
