7.3.3
FLL engaged internal (FEI) is entered when any of the following conditions occur:
In FLL engaged internal mode, the reference clock is derived from the internal reference clock
ICGIRCLK, and the FLL loop will attempt to lock the ICGDCLK frequency to the desired value, as
selected by the MFD bits.
7.3.3.1
FEI unlocked is a temporary state that is entered when FEI is entered and the count error (∆n) output from
the subtractor is greater than the maximum n
lock detector to detect the unlock condition.

CLKS bits are written to 01
The DCO clock stabilizes (DCOS = 1) while in SCM upon exiting the off state with CLKS = 01
