12.4.1
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.
12.4.1.1
FLL engaged internal (FEI) is the default mode of operation and is entered when all the following
conditions occur:

IREFS=1
CLKS=01
BDM Disabled
and LP=1

•
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.
