INPUT CAPTURE MODULE
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
These operating modes are determined by setting the
appropriate bits in the ICxCON register (where x =
1,2,...,N). The dsPIC30F6010 device has 8 capture
channels.
12.1
Simple Capture Event Mode
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
CAPTURE PRESCALER
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.
