12.0
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.
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
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).

12.1
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>).
12.1.1
There are four input capture prescaler settings speci-
fied by bits ICM<2:0> (ICxCON<2:0>). Whenever the
capture channel is turned off, the prescaler counter will
be cleared. In addition, any Reset will clear the
prescaler counter.
