A.5 Reset, Oscillator and PLL
This section summarizes the electrical characteristics of the various startup scenarios for Oscillator and
Phase-Locked-Loop (PLL).
A.5.1 Startup
Table A-14
summarizes several startup characteristics explained in this section. Detailed description of
the startup behavior can be found in the Clock and Reset Generator (CRG) Block User Guide.
Table A-14 Startup Characteristics
A.5.1.1 POR
The release level V
PORR
and the assert level V
PORA
are derived from the V
DD
Supply. They are also valid
ifthedeviceispoweredexternally.AfterreleasingthePORresettheoscillatorandtheclockqualitycheck
are started. If after a time t
CQOUT
no valid oscillation is detected, the MCU will start using the internal self
clock. The fastest startup time possible is given by n
uposc
.
A.5.1.2 SRAM Data Retention
Provided an appropriate external reset signal is applied to the MCU, preventing the CPU from executing
codewhenVDD5isoutofspecificationlimits,theSRAMcontentsintegrityisguaranteedifafterthereset
the PORF bit in the CRG Flags Register has not been set.
A.5.1.3 External Reset
When external reset is asserted for a time greater than PW
RSTL
the CRG module generates an internal
reset, and the CPU starts fetching the reset vector without doing a clock quality check, if there was an
oscillation before reset.
A.5.1.4 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.
