The use of the filter function is only possible if the VCOCLK-to-OSCCLK ratio divided by two ((f
f
If enabled, the oscillator filter is sampling the incoming oscillator clock signal (EXTAL) with the
VCOCLK frequency.
Using VCOCLK, a time window is defined during which an edge of the OSCCLK is expected. In case of
OSCBW = 1 the width of this window is three VCOCLK cycles, if the OSCBW = 0 it is one VCOCLK
cycle.
The noise detection is active for certain combinations of OSCFILT[4:0] and OSCBW bit settings as shown

)/2) is an integer number. This integer value must be written to the OSCFILT[4:0] bits.
If the VCOCLK frequency is higher than 25 MHz the wide bandwidth must
be selected (OSCBW = 1).
