The ICS presents the divided FLL reference clock as ICSFFCLK for use as an additional clock
source. ICSFFCLK frequency must be no more than 1/4 of the ICSOUT frequency to be valid.
Local Clock
The ICS presents the low range DCO output clock divided by two as ICSLCLK for use as a clock source
for BDC communications. ICSLCLK is not available in FLL bypassed internal low-power (FBILP) and
FLL bypassed external low-power (FBELP) modes.
