16.7.7 Receive data noise filter
obtained twice, the match detector output changes, and this output is sampled as input data. Therefore, data not
exceeding one clock width is judged to be noise and is not delivered to the internal circuit (see Figure 16-9).

The RXDBn signal is sampled at the rising edge of the peripheral clock (f
Also, since the circuit is configured as shown in Figure 16-8, internal processing during a receive operation is
