This section describes the input capture module and
associated operational modes. The features provided by
this module are useful in applications requiring
frequency (period) and pulse measurement.
depicts a block diagram of the input capture module.
Input capture is useful for such modes as:
• Frequency/Period/Pulse Measurements
• Additional Sources of External Interrupts

From General Purpose Timer Module
The key operational features of the input capture
module are:
• Simple Capture Event mode
• Timer2 and Timer3 mode selection
• Interrupt on input capture event
These operating modes are determined by setting
the appropriate bits in the ICxCON register
(where x = 1,2,...,N).

The dsPIC30F3010/3011 devices have
four capture channels. The channels are
designated IC1, IC2, IC7 and IC8 to
maintain software compatibility with other
dsPIC30F devices.
