10.4.1
The seven states of the ICS are shown as a state diagram and are described below. The arrows indicate the
allowed movements between the states.
10.4.1.1
FLL engaged internal (FEI) is the default mode of operation and is entered when all the following
conditions occur:
Freescale Semiconductor
FLL Bypassed
External Low

IREFS=0
CLKS=10
BDM Disabled

Functional Description
Operational Modes
OSC Initialization — If the external reference clock is selected by ERCLKEN or by the ICS being in FEE, FBE,
or FBELP mode, and if EREFS is set, then this bit is set after the initialization cycles of the external oscillator
clock have completed. This bit is only cleared when either ERCLKEN or EREFS are cleared.
ICS Fine Trim — The FTRIM bit controls the smallest adjustment of the internal reference clock frequency.
Setting FTRIM will increase the period and clearing FTRIM will decrease the period by the smallest amount
possible.
