The decision of the logic level of the received bit is taken by doing a majority voting of the logic
value to the three samples in the center of the received bit. The center samples are empha-
sized on the figure by having the sample number inside boxes. The majority voting process is
done as follows: If two or all three samples have high levels, the received bit is registered to be
a logic 1. If two or all three samples have low levels, the received bit is registered to be a logic
0. This majority voting process acts as a low pass filter for the incoming signal on the RxDn
pin. The recovery process is then repeated until a complete frame is received. Including the
first stop bit. Note that the Receiver only uses the first stop bit of a frame.

bit of the next frame.
The same majority voting is done to the stop bit as done for the other bits in the frame. If the
stop bit is registered to have a logic 0 value, the Frame Error (FEn) Flag will be set.
A new high to low transition indicating the start bit of a new frame can come right after the last
of the bits used for majority voting. For Normal Speed mode, the first low level sample can be
at point marked (A) in
to (B). (C) marks a stop bit of full length. The early start bit detection influences the operational
range of the Receiver.
