LP-MSPM0C1104: Cannot find GPIO Peripheral functionality (PF) IDs for different functionality in Reference or Datasheet

Tool/software:

So I am trying to see what different PF IDs in the PINCMx Register. The ID is a 6 bit value and i cannot find the exact ID for a certain functionality. But I can see in the ide the different numbers mapped in the device Header file. Where can I find this IOMUX ID mapped details?
