B.4.1.4 External Reset
When external reset is asserted for a time greater than PW
the CRG module generates an internal
RSTL
reset, and the CPU starts fetching the reset vector without doing a clock quality check, if there was an
oscillation before reset.
B.4.1.5 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.
B.4.1.6 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. The controller can be woken up by internal or external interrupts. After t
the CPU starts
wrs
fetching the interrupt vector.
