The nine states of the MCG are shown as a state diagram and are described below. The arrows indicate the
allowed movements between the states.
8.4.1.1
FLL engaged internal (FEI) is the default mode of operation and is entered when all the following
conditions occur:
In FLL engaged internal mode, the MCGOUT clock is derived from the FLL clock, which is controlled by
the internal reference clock. The FLL clock frequency locks to a multiplication factor, as selected by the
DRS and DMX32 bits, times the internal reference frequency. The MCGLCLK is derived from the FLL
and the PLL is disabled in a low power state.
8.4.1.2
The FLL engaged external (FEE) mode is entered when all the following conditions occur:
In FLL engaged external mode, the MCGOUT clock is derived from the FLL clock which is controlled by
the external reference clock. The external reference clock which is enabled can be an external
crystal/resonator or it can be another external clock source.The FLL clock frequency locks to a
multiplication factor, as selected by the DRS and DMX32 bits, times the external reference frequency, as
selected by the RDIV, RANGE and DIV32 bits. The MCGLCLK is derived from the FLL and the PLL is
disabled in a low power state.
8.4.1.3
In FLL bypassed internal (FBI) mode, the MCGOUT clock is derived from the internal reference clock
and the FLL is operational but its output clock is not used. This mode is useful to allow the FLL to acquire
its target frequency while the MCGOUT clock is driven from the internal reference clock.
The FLL bypassed internal mode is entered when all the following conditions occur:
In FLL bypassed internal mode, the MCGOUT clock is derived from the internal reference clock. The FLL
clock is controlled by the internal reference clock, and the FLL clock frequency locks to a multiplication
