Functional Description
3.6.1.6 Windowed/Resampled Mode (6)
This example uses the same input stimulus shown in Figure 4-9, and adds resampling of
COUTA to generate COUT. Samples are taken at the time points indicated by the arrows.
Again, prop delays and latency are ignored for clarity’s sake. This example was
generated solely to demonstrate operation of the comparator in windowing / resampled
mode, and does not reflect any specific application. Depending upon the sampling rate
and window placement, COUT may not see zero-crossing events detected by the analog
comparator. Sampling period and/or window placement must be carefully considered for
a given application.
This mode of operation results in an unfiltered string of comparator samples where the
interval between the samples is determined by FILT_PER and the peripheral clock rate.
Configuration for this mode is virtually identical to that for the windowed/filtered mode
shown in the next section. The only difference is that the value of FILTER_CNT must be
exactly one.
