ICG Status Register 2 (ICGS2)
ICG Filter Registers (ICGFLTU, ICGFLTL)
DCO Clock Stable — 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.
0 DCO clock is unstable.
1 DCO clock is stable.
Filter Value — The FLT bits indicate the current filter value, which controls the DCO frequency. The FLT bits are
read only except when the CLKS bits are programmed to self-clocked mode (CLKS = 00). In self-clocked mode,
any write to ICGFLTU updates the current 12-bit filter value. Writes to the ICGFLTU register will not affect FLT if
a previous latch sequence is not complete.
