This section describes the Input Capture module and
associated operational modes. The features provided
by this module are useful in applications requiring Fre-
quency (Period) and Pulse measurement. Figure 11-1
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 dsPIC DSC devices contain up to 8
capture channels, (i.e., the maximum value of N is 8).

The dsPIC30F2010 device has four
capture inputs – IC1, IC2, IC7 and IC8.
The naming of these four capture chan-
nels is intentional and preserves software
compatibility with other dsPIC DSC
devices.
