Allowable baud rate range during reception

The degree to which a discrepancy from the transmission destination’s baud rate is allowed during
reception is shown below.

Caution: The equations described below should be used to set the baud rate error during

reception so that it always is within the allowable error range.

Figure 12-19: Allowable Baud Rate Range During Reception

As shown in Figure 12-19, after the start bit is detected, the receive data latch timing is determined
according to the counter that was set by the BRGCm register. If all data up to the final data (stop bit)
is in time for this latch timing, the data can be received normally.
Applying this to 11-bit reception is, theoretically, as follows.

FL = BR

-1

BR: UARTn baud rate
k:

BRGCm register setting value

FL: 1-bit data length

When the latch timing margin is made 2 basic clocks (Clock), the minimum allowable transfer rate
(FLmin) is as follows.

Therefore, the transfer destination’s maximum baud rate (BRmax) that can be received is as fol-
lows.
