— Uses external or internal clock as reference frequency
Automatic lockout of non-running clock sources
Reset or interrupt on loss of clock or loss of FLL lock
Digitally-controlled oscillator (DCO) preserves previous frequency settings, allowing fast
frequency lock when recovering from stop3 mode
DCO will maintain operating frequency during a loss or removal of reference clock. When FLL is
engaged (FEE or FEI) loss of lock or loss of clock adds a divide-by-2 to ICG to prevent
over-clocking of the system.
Post-FLL divider selects 1 of 8 bus rate divisors (/1 through /128)
Separate self-clocked source for real-time interrupt
Trimmable internal clock source supports SCI communications without additional external
components
Automatic FLL engagement after lock is acquired
Selectable low-power/high-gain oscillator modes
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
to lock. The FLL DCO frequency is off target and the FLL is adjusting the DCO to match the
target frequency.

to lock. The FLL DCO frequency is off target and the FLL is adjusting the DCO to match the
target frequency.
