Figure 15.21
The state of the SCL and SDA pins are routed through the noise rejection circuit before being latched
internally. Figure 15.21 shows the Block Diagram of Noise Rejection Circuit.
The noise rejection circuit consists of two cascaded latch and match detector circuits. When the SCL
pin input signal (or SDA pin input signal) is sampled on f1 and 2 latch outputs match, the level is
passed forward to the next circuit. When they do not match, the former value is retained.
