11.0
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.

capture module. Input capture is useful for such modes
as:
• Frequency/Period/Pulse Measurements
• Additional Sources of External Interrupts
Important 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 IC1CON and IC2CON registers.
The dsPIC30F2011/2012/3012/3013 devices have two
capture channels.
11.1
The simple capture events in the dsPIC30F product
family are:
• Capture every falling edge
• Capture every rising edge
• Capture every 4th rising edge
• Capture every 16th rising edge
• Capture every rising and falling edge
These simple Input Capture modes are configured by
setting the appropriate bits, ICM<2:0> (ICxCON<2:0>).
11.1.1
There are four input capture prescaler settings
specified by bits ICM<2:0> (ICxCON<2:0>). Whenever
the capture channel is turned off, the prescaler counter
is cleared. In addition, any Reset clears the prescaler
counter.
