7.2 Clocks after Reset
The device selects the OSC16M oscillator which is enabled by default after reset and configured at 4 MHz.
This 4 MHz clock is also the default time base for the
Generic Clock Generator 0 which provides the main clock (CLK_MAIN) to the system through
the GCLK_MAIN clock.
Note: Other generic
clocks are disabled to optimize the power consumption.
The OSCULP32K is also enabled by default after reset and is used as source for different peripherals requiring a default slow clock source.
