(5) Data frame length during continuous transmission
216
When data is continuously transmitted, the data frame length from a stop bit to the next start bit is extended by
two clocks of the base clock (f
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
