10.1.4.4

FLL Bypassed Internal Low Power (FBILP)

In FLL bypassed internal low power mode, the FLL is disabled and bypassed, and the ICS supplies a clock

derived from the internal reference clock. The BDC clock is not available.

10.1.4.5

FLL Bypassed External (FBE)

In FLL bypassed external mode, the FLL is enabled and controlled by an external reference clock, but is

bypassed. The ICS supplies a clock derived from the external reference clock. The external reference clock

can be an external crystal/resonator supplied by an OSC controlled by the ICS, or it can be another external

clock source. The BDC clock is supplied from the FLL.

10.1.4.6

FLL Bypassed External Low Power (FBELP)

In FLL bypassed external low power mode, the FLL is disabled and bypassed, and the ICS supplies a clock

derived from the external reference clock. The external reference clock can be an external crystal/resonator

supplied by an OSC controlled by the ICS, or it can be another external clock source. The BDC clock is

not available.

10.1.4.7

Stop (STOP)

In stop mode the FLL is disabled and the internal or external reference clocks can be selected to be enabled

or disabled. The BDC clock is not available and the ICS does not provide an MCU clock source.

10.2

External Signal Description

There are no ICS signals that connect off chip.
