(3) Input Capture
The input capture module performs the functions of detecting the rising edge, falling edge, or both edges of
signal input from external circuits, and saving the 16-bit free-run timer value at that moment to a register. An
interrupt can also be generated at the instant of edge detection.
The input capture module consists of input capture registers and a control register. Each input capture module
has its own external input pin.
Selection of three types of valid edge for external input signals.
Rising edge, falling edge, both edges.
An interrupt can be generated when a valid edge is detected in the external input signal.
