9.4.1.2
The FLL engaged external (FEE) mode is entered when all the following conditions occur:
In FLL engaged external mode, the ICSOUT clock is derived from the FLL clock which is controlled by
the external reference clock.The FLL loop will lock the frequency to 512 times the filter frequency, as
selected by the RDIV bits. The ICSLCLK is available for BDC communications, and the external
reference clock is enabled.
9.4.1.3
The FLL bypassed internal (FBI) mode is entered when all the following conditions occur:
In FLL bypassed internal mode, the ICSOUT clock is derived from the internal reference clock. The FLL
clock is controlled by the internal reference clock, and the FLL loop will lock the FLL frequency to 512
times the Filter frequency, as selected by the RDIV bits. The ICSLCLK will be available for BDC
communications, and the internal reference clock is enabled.
9.4.1.4
The FLL bypassed internal low power (FBILP) mode is entered when all the following conditions occur:
In FLL bypassed internal low power mode, the ICSOUT clock is derived from the internal reference clock
and the FLL is disabled. The ICSLCLK will be not be available for BDC communications, and the internal
reference clock is enabled.
9.4.1.5
The FLL bypassed external (FBE) mode is entered when all the following conditions occur:
In FLL bypassed external mode, the ICSOUT clock is derived from the external reference clock. The FLL
clock is controlled by the external reference clock, and the FLL loop will lock the FLL frequency to 512
