17.6.10 Receive data noise filter
the input data. Therefore, data not exceeding 2 clock width is judged to be noise and is not delivered to the internal circuit
(see Figure 17-18). See 17.7 (1) (a) Base clock regarding the base clock.

This filter samples the RXDCn pin using the base clock of the prescaler output.
When the same sampling value is read twice, the match detector output changes and the RXDCn signal is sampled as
Moreover, since the circuit is as shown in Figure 17-17, the processing that goes on within the receive operation is
