SETTLING_COUNT

Number of undivided reference clock cycles to wait after changing the CCO trim until the loop measurement restarts. A delay allows the CCO output to settle and gives a more accurate measurement. The default is tuned to an 8MHz reference clock since the IMO is expected to be the most common use case. 0: no settling time 1: wait one reference clock cycle … 8191: wait 8191 reference clock cycles

BYPASS_SEL

Bypass mux located just after FLL output.

0 (AUTO): Automatic using lock indicator. When unlocked, automatically selects FLL reference input (bypass mode). When locked, automatically selects FLL output.

1 (AUTO1): Same as AUTO

2 (FLL_REF): Select FLL reference input (bypass mode). Ignores lock indicator

3 (FLL_OUT): Select FLL output. Ignores lock indicator.
