(6) Data frame length during continuous transmission
In continuous transmission, the data frame length from the stop bit to the next start bit is 2 base clock cycles
longer than usual. However, timing initialization is performed via start bit detection by the receiving side, so
this has no influence on the transfer result.
Assuming a 1 bit data length of BL; a stop bit length of BLstp; and a base clock frequency of f
the following equation.
Therefore, the transfer rate during continuous transmission is as follows.
BLstp = BL + 2/f
Data frame length = 11 × BL + (2/f
