CMP Functional Description
When any windowed mode is active, COUTA is clocked by the bus clock whenever
WINDOW = 1. The last latched value is held when WINDOW = 0.
32.8.1.6 Windowed/Resampled Mode (# 6)
The following figure uses the same input stimulus shown in
resampling of COUTA to generate COUT. Samples are taken at the time points indicated
by the arrows. Again, prop delays and latency is 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 FPR[FILT_PER] and the bus 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 CR0[FILTER_CNT]
must be exactly one.
