(4) Permissible baud rate range during reception
446
The permissible error from the baud rate at the transmission destination during reception is shown below.
Caution Make sure that the baud rate error during reception is within the permissible error range, by
As shown in Figure 14-26, the latch timing of the receive data is determined by the counter set by baud rate
generator control register 6 (BRGC6) after the start bit has been detected. If the last data (stop bit) meets this
latch timing, the data can be correctly received.
Assuming that 11-bit data is received, the theoretical values can be calculated as follows.
