(6) Baud rate during continuous transmission
During continuous transmission, the transfer rate from the stop bit to the next start bit is usually 2 base clocks
longer. However, timing initialization is performed via start bit detection by the receiving side, so this has no
influence on the transfer result.
Assuming 1 bit data length: FL; stop bit length: FLstp; and base clock frequency: f
equation.
Therefore, the transfer rate during continuous transmission is as follows.
FLstp = FL + 2/f
Transfer rate = 11 × FL + (2/f
