Figure 21-4. Main Clock Selection
MOSCRCEN, MOSCXTEN, MOSCSEL and MOSCXTBY bits are located in the PMC Clock
Generator Main Oscillator Register (CKGR_MOR).
After a VDDBU power on reset, the default configuration is MOSCRCEN = 1, MOSCXTEN = 0
and MOSCSEL = 0, the 12 MHz RC oscillator is started as Main clock.
To speed up the wake-up phase, the system boots on 12 MHz RC (Main Clock). This allows the
user to perform system configuration (PLL, DDR2, etc.) at 12 MHz instead of 32 kHz during
12 MHz oscillator start-up.
Wait MOSCRCS = 1
