Chapter 8 Multi-Purpose Clock Generator (S08MCGV1)
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 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.
8.4.1.4
In FLL bypassed external (FBE) mode, the MCGOUT clock is derived from the external 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 external reference clock.
The FLL bypassed external mode is entered when all the following conditions occur:
In FLL bypassed external mode, the MCGOUT clock is derived from 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 is controlled by the external reference clock, and 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.
8.4.1.5
The PLL engaged external (PEE) mode is entered when all the following conditions occur:
In PLL engaged external mode, the MCGOUT clock is derived from the PLL 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 PLL clock frequency locks to a

It is possible to briefly operate in FBE mode with an FLL reference clock
frequency that is greater than the specified maximum frequency. This can be
necessary in applications that operate in PEE mode using an external crystal
with a frequency above 5 MHz. Please see
from FEI to PEE Mode: External Crystal = 8 MHz, Bus Frequency = 8 MHz
for a detailed example.
