. A 2-bit counter is shown for convenience, the operation of wider counters is

similar. The output of the filter switches from 1 to 0, when the counter counts down from
to

11b.
The noise filter delays the receive data by three System Clock cycles.
The FiltSatB signal is checked when the filtered RxD is sampled in the center of the bit
time. The presence of noise (
at center of bit time) does not mean that the
FiltSatB = 1
sampled data is incorrect, but just that the filter is not in its ‘saturated’ state of all 1s or 
all 0s. If FiltSatB = 1 then RxD is sampled during a receive character, the
bit in the
NE
field is set. By observing this bit, an indication of the level of noise in
ModeStatus[4:0]
the network can be obtained.
