The logic levels at the SCL and SDA pins are routed through noise filters before being latched
internally. Figure 17.17 shows a block diagram of the noise filter circuit.
The noise filter consists of three cascaded latches and a match detector. The SCL (or SDA) input
signal is sampled on the peripheral clock. When NF2CYC is set to 0, this signal is not passed
forward to the next circuit unless the outputs of both latches agree. When NF2CYC is set to 1, this
signal is not passed forward to the next circuit unless the outputs of three latches agree. If they do
not agree, the previous value is held.
