1. FIQ Initialization
2. Stack setup for ARM supervisor mode
3. External Clock Detection
4. Switch Master Clock on Main Oscillator
5. C variable initialization
6. Main oscillator frequency detection if no external clock detected
7. PLL setup: PLLB is initialized to generate a 48 MHz clock necessary to use the USB
Device. A register located in the Power Management Controller (PMC) determines the
frequency of the main oscillator and thus the correct factor for the PLLB.
a. If Internal RC Oscillator is used (OSCSEL = 0) and Main Oscillator is active,
b. If Internal RC Oscillator is used (OSCSEL = 0) and Main Oscillator is bypassed,
c. If an external 32768 Hz Oscillator is used (OSCSEL = 1),
Any other crystal can be used but it prevents using the USB.
Any other input frequency can be used but it prevents using the USB.
Booting either on USB or on DBGU is possible with any of these crystals.
