ICG Control Register 2 (ICGC2)
Loss of Lock Reset Enable — The LOLRE bit determines what type of request is made by the ICG following a
loss of lock indication. The LOLRE bit only has an effect when LOLS is set.

Multiplication Factor — The MFD bits control the programmable multiplication factor in the FLL loop. The value
specified by the MFD bits establishes the multiplication factor (N) applied to the reference frequency. Writes to
the MFD bits will not take effect if a previous write is not complete. Select a low enough value for N such that

Reduced Frequency Divider — The RFD bits control the value of the divider following the clock select circuitry.
The value specified by the RFD bits establishes the division factor (R) applied to the selected output clock source.
Writes to the RFD bits will not take effect if a previous write is not complete.
