A.4 Reset, Oscillator and PLL
This section summarizes the electrical characteristics of the various startup scenarios for Oscillator and
Phase-Locked-Loop (PLL).
A.4.1 Startup
Table A-13 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.
A.4.1.1 POR
The release level V
if the device is powered externally. After releasing the POR reset the oscillator and the clock quality check
are started. If after a time t
clock. The fastest startup time possible is given by n
A.4.1.2 SRAM Data Retention
Provided an appropriate external reset signal is applied to the MCU, preventing the CPU from executing
code when VDD5 is out of specification limits, the SRAM contents integrity is guaranteed if after the reset
the PORF bit in the CRG Flags Register has not been set.
A.4.1.3 External Reset
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.
