12.0
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. Figure 12-1
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
The key operational features of the input capture
module are:
• Simple Capture Event mode
• Timer2 and Timer3 mode selection
• Interrupt on input capture event

This data sheet summarizes features of
this group of dsPIC30F devices and is not
intended to be a complete reference
source. For more information on the CPU,
peripherals, register descriptions and
general device functionality, refer to the
“dsPIC30F Family Reference Manual”
(DS70046). For more information on the
device instruction set and programming,
refer to the “dsPIC30F/33F Programmer’s
Reference Manual” (DS70157).
Where ‘x’ is shown, reference is made to the registers or bits associated to the respective input
capture channels 1 through N.

These operating modes are determined by setting the
appropriate
(where x = 1,2,...,N). The dsPIC30F5015/5016 device
has 8 capture channels.
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,
specified 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.
