Chapter 7 AC Zero-Cross Circuit/Noise Filter

7-3-2 Example Input and Output Waveforms for Noise Filter

When the noise filter is used, the waveform input to the IRQ0 pin is sampled based on the clock specified by the NF0CKS0 and NF0CKS1 flags of the noise filter control register (NFCTR). The waveform input to the IRQ1 pin is also sampled based on the clock specified

by the NF1CKS0 and NF1CKS1 flags. If the sampled level remains the same for 3

consecutive samples, it is sent the CPU; otherwise, the previous level is maintained.

Waveform after noise filtering

Noise filtering cannot be

used in the STOP or HALT

modes.
