the signal five times. It accepts a level input which is continuous at least over the period of time required for
five samplings. Any level input which does not continue over the period of time required for five samplings is
canceled as noise.
A digital noise canceller eliminates noise from the input signal on the TC7 pin.
The digital noise canceller uses a sampling clock of fc/4, fc/2 or fc, as specified with NCRSEL, and samples

data register (TC7DRC). To start the counter, use start control (TC7S) in command start and capture
