(5) Data frame length during continuous transmission

When data is continuously transmitted, the data frame length from a stop bit to the next start bit is extended by two
clocks of base clock from the normal value. However, the result of communication is not affected because the timing
is initialized on the reception side when the start bit is detected.
Where the 1-bit data length is FL, the stop bit length is FLstp, and base clock frequency is f
expression is satisfied.
Therefore, the data frame length during continuous transmission is:
FLstp = FL + 2/f
Data frame length = 11 × FL + 2/f
