(3) Input Capture
The input capture consists of two independent external input pins, their corresponding capture registers, and
a control register. The value of the 16-bit free-run timer can be stored in the capture register and an interrupt
generated when the specified edge is detected on the signal from the external input pin.
The edge to detect on the external input signal is selectable.
Detection of rising edges, falling edges, or either edge can be specified.
The two input capture channels can operate independently.
An interrupt can be generated on detection of the specified edge on the external input signal.
The input capture interrupt can activate the intelligent I/O service.
Register details
The 16-bit free-run timer value is stored in these registers when the specified edge is detected on the input
waveform from the corresponding external pin. (Always use word access. Writing is prohibited.)
