Internal Clock Generator (ICG) Module
ICGIF — ICG Interrupt Flag
7.5.4
DCOS — DCO Clock Stable
7.5.5
122
The ICGIF read/write flag is set when an ICG interrupt request is pending. It is cleared by a reset or
by reading the ICG status register when ICGIF is set and then writing a 1 to ICGIF. If another ICG
interrupt occurs before the clearing sequence is complete, the sequence is reset so ICGIF would remain
set after the clear sequence was completed for the earlier interrupt. Writing a 0 to ICGIF has no effect.
The DCOS bit is set when the DCO clock (ICG2DCLK) is stable, meaning the count error has not
changed by more than n
used when exiting off state if CLKS = X1 to determine when to switch to the requested clock mode. It
is also used in self-clocked mode to determine when to start monitoring the DCO clock. This bit is
cleared upon entering the off state.
1 = An ICG interrupt request is pending.
0 = No ICG interrupt request is pending.
1 = DCO clock is stable.
0 = DCO clock is unstable.
