7.5.8. Recalibrating the fPLL

Note: Address refers to the fPLL offset address.
  1. Perform a RMW operation on 0x02 with mask 0x02 to address 0x100. This sets the fPLL calibration enable bit.
  2. Write 0x01 to address 0x00. This lets the PreSICE perform the calibration.
  3. Loop read 0x480[1] until you see it become 0x0.
    fPLL calibration is complete when 0x480[1] = 0x0.
