Mode 1 — Off
The output clock, ICGOUT, is static. This mode may be entered when the STOP instruction is
executed.
Mode 2 — Self-clocked (SCM)
Default mode of operation that is entered out of reset. The ICG’s FLL is open loop and the digitally
controlled oscillator (DCO) is free running at a frequency set by the filter bits.
Mode 3 — FLL engaged internal (FEI)
In this mode, the ICG’s FLL is used to create frequencies that are programmable multiples of the
internal reference clock.
— FLL engaged internal unlocked is a transition state which occurs while the FLL is attempting
— FLL engaged internal locked is a state which occurs when the FLL detects that the DCO is
Mode 4 — FLL bypassed external (FBE)
In this mode, the ICG is configured to bypass the FLL and use an external clock as the clock source.
Mode 5 — FLL engaged external (FEE)
The ICG’s FLL is used to generate frequencies that are programmable multiples of the external
clock reference.
— FLL engaged external unlocked is a transition state which occurs while the FLL is attempting
— FLL engaged external locked is a state which occurs when the FLL detects that the DCO is
