The noise canceller circuit built into the H8/3834 Series is a digital low-pass filter that rejects
high-frequency pulse noise in the input at the input capture pin. The noise canceller circuit is
enabled by the noise canceller select (NCS)* bit in port mode register 2 (PMR2).
Figure 9.9 shows a block diagram of the noise canceller circuit.
