LOLRE
Enable Oscillator in Off Mode — The OSCSTEN bit controls whether or not the oscillator circuit remains
enabled when the ICG enters off mode. This bit has no effect if HGO = 1 and RANGE = 1.
0 Oscillator disabled when ICG is in off mode unless ENABLE is high, CLKS = 10, and REFST = 1.
1 Oscillator enabled when ICG is in off mode, CLKS = 1X and REFST = 1.
Loss of Clock Disable
0 Loss of clock detection enabled.
1 Loss of clock detection disabled.
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
