Note:
- This PLL is powered by the 2.5V regulated output of the VDDOUT25 regulator, which is supplied from VDDIN33.
- Simulation data
- For optimal setting of the PLLA, set the register PMC_PLL_ACR to the value 0x00020010.

Note:
- This PLL is powered by an internal dedicated voltage regulator, supplied from VDDIN33, that must be started by software before enabling this PLL. Refer to Clock Generator.
- Only 12, 16, 24 or 48 MHz input frequencies are authorized to support USB-related features of the bootloader program in ROM.
- Covers the startup time of the PLL and of its dedicated voltage regulator.
- The post divider is hardwired in a divide-by-2 configuration.
- Simulation data
- For optimal setting of the PLLUTMI, set the PMC_PLL_ACR as follows:
PMC_PLL_ACR = 0x09023010 for fIN = [12 MHz, 18 MHz[
PMC_PLL_ACR = 0x12023010 for fIN = [18 MHz, 32 MHz[
PMC_PLL_ACR = 0x1B023010 for fIN = [32 MHz, 48 MHz]
