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
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
External oscillator selectable for low power or high gain
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 immediately after 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.
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 that occurs while the FLL is attempting to
— FLL engaged internal locked is a state that occurs when the FLL detects that the DCO is locked
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 that occurs while the FLL is attempting to
— FLL engaged external locked is a state which occurs when the FLL detects that the DCO is
Mode 3 — FLL engaged internal (FEI)
Modes of Operation
