This filter samples signals received via the RXDAn pin using the base clock supplied by the dedicated baud rate
When the same sampling value is read twice, the match detector output changes and the RXDAn signal is sampled
Moreover, since the circuit is as shown in Figure 16-15, the processing that goes on within the receive operation is
