Figure 15-3 depicts a capture event when the input
capture module is in Prescaler Capture Event mode.
FIGURE 15-3:

In Edge Detect mode, the input capture module cap-
tures a timer count value on every edge of the capture
input. Edge Detect mode is selected by setting the ICM
bit to ‘001’. In this mode, the capture prescaler is not
used and the capture overflow bit, ICOV (ICxCON<4>)
is not updated. In this mode, the Interrupt Control bits
(ICI, ICxCON<6:5>) are ignored and an interrupt event
is generated for every timer count capture

active mode does not reset the prescaler
and may cause an inadvertent capture
event.

When the Input Capture module is set for Interrupt
Only mode (ICM = ‘111’) and the device is in Sleep or
Idle mode, the capture input functions as an interrupt
pin. Any rising edge on the capture input triggers an
interrupt. No timer values are captured and the FIFO
buffer is not updated. When the device leaves Sleep or
Idle mode, the interrupt signal is deasserted.
In this mode, since no timer values are captured, the
Timer Select bit ICTMR (ICxCON<7>) is ignored and
there is no need to configure the timer source. A wake-
up interrupt is generated on the first rising edge, there-
fore the Interrupt Control bits ICI (ICxCON<6:5>) are
also ignored. The prescaler is not used in this mode.
