The Trigger/Sync source is enabled by default and is set to Timer3 as a source. This timer must be enabled for
proper ICx module operation or the Trigger/Sync source must be changed to another source option.

The Input Capture module is useful in applications
requiring frequency (period) and pulse measurement.
The dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/
50X, and PIC24EPXXXGP/MC20X devices support up
to four input capture channels.
Key features of the Input Capture module include:
• Hardware-configurable for 32-bit operation in all
• Synchronous and Trigger modes of output
• A 4-level FIFO buffer for capturing and holding
• Configurable interrupt generation
• Up to six clock sources available for each module,
16
modes by cascading two adjacent modules
compare operation, with up to 31 user-selectable
trigger/sync sources available
timer values for several events
driving a separate internal 16-bit counter
