(g) Noise filter of receive data
The RXD6 signal is sampled with the base clock output by the prescaler block.
If two sampled values are the same, the output of the match detector changes, and the data is sampled as
input data.
Because the circuit is configured as shown in Figure 10-16, the internal processing of the reception operation
is delayed by two clocks from the external signal status.
