Appendix A Electrical Characteristics
A.4.1.3
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.4.1.4
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.4.1.5
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.
A.4.1.6
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 performance takes t
can be woken up by internal or external interrupts.After t
starts fetching the interrupt vector.
A.4.2
The device features an internal Colpitts and Pierce oscillator. The selection of Colpitts oscillator or Pierce
oscillator/external clock depends on the XCLKS signal which is sampled during reset. Pierce
oscillator/external clock mode allows the input of a square wave. Before asserting the oscillator to the
internal system clocks the quality of the oscillation is checked for each start from either power-on, STOP
or oscillator fail. t
POR or STOP if a proper oscillation is not detected. The quality check also determines the minimum
oscillator start-up time t
asserted if the frequency of the incoming clock signal is below the Assert Frequency f
