AM68A: Power Estimation Tool: MCU PLL 0 setting, which values are valid?

Team,

I tried the power estimation tool (SPRUJ91). But there is something strange with the MCU PLL 0 setting. 

Defaul value is 1000 MHz. But in the drop-down menu for the cell, you can only select 250 or 33 MHz. No way to go back to 1000 MHz, or to change a different value like e.g. 500 MHz. 

Can you please let me know which values are really supported?

Thanks,
  Robert
