17.4.7
The signal levels on the SCL and SDA pins are internally latched via the noise filter. Figure 17.16
shows a block diagram of the noise filter circuit.
The noise filter consists of two cascaded latches and a match detector. The SCL (or SDA) input
signal is sampled on the system clock. When both outputs of the latches match, its level is output
to other blocks by the match detector. If they do not match, the previous value is held.
