(b) Timing of capture trigger edge detection
The Tin inputs are fitted with an edge-detection and noise-elimination circuit.
Because of this circuit, 3 periods to less than 4 periods of the count clock are
required from edge input until an interrupt signal is output and capture
operation is performed. The timing chart is shown below.
Basic settings (x = 0, 1 and y = 0 to 5):
