    Figure 20-7. Stop Bit Sampling and Next Start Bit Sampling
    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 Figure 20-7. For Double Speed mode the first low level must be delayed to
    (B). (C) marks a stop bit of full length. The early start bit detection influences the operational
    range of the Receiver.
    20.8.3
    Asynchronous Operational Range
    The operational range of the Receiver is dependent on the mismatch between the received bit
    rate and the internally generated baud rate. If the Transmitter is sending frames at too fast or too
    slow bit rates, or the internally generated baud rate of the Receiver does not have a similar (see
    Table 20-2) base frequency, the Receiver will not be able to synchronize the frames to the start
    bit.
    The following equations can be used to calculate the ratio of the incoming data rate and internal
    receiver baud rate.
    D
    Sum of character size and parity size (D = 5 to 10 bit)
    S
    Samples per bit. S = 16 for Normal Speed mode and S = 8 for Double Speed
    mode.
    S
    F
    First sample number used for majority voting. S
    F = 8 for normal speed and SF = 4
    for Double Speed mode.
    S
    M
    Middle sample number used for majority voting. S
    M = 9 for normal speed and
    S
    M = 5 for Double Speed mode.
    R
    slow
    is the ratio of the slowest incoming data rate that can be accepted in relation to the
    receiver baud rate. R
    fast is the ratio of the fastest incoming data rate that can be
    accepted in relation to the receiver baud rate.
    Table 20-2 and Table 20-3 list the maximum receiver baud rate error that can be tolerated. Note
    that Normal Speed mode has higher toleration of baud rate variations.
