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 1024 times the reference frequency, as
selected by the RDIV bits. 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 1024 times
the reference frequency, as selected by the RDIV 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:

CLKS bits are written to 00
IREFS bit is written to 1
PLLS bit is written to 0
RDIV bits are written to 000. Since the internal reference clock frequency should already be in the
range of 31.25 kHz to 39.0625 kHz after it is trimmed, no further frequency divide is necessary.
