FIGURE 17-14:
17.4
The IC and QEI submodules can each generate three
distinct interrupt signals; however, they share the use
of the same three interrupt flags in register, PIR3. The
meaning of a particular interrupt flag at any given time
depends on which module is active at the time the
interrupt is set. The meaning of the flags in context are
summarized in
When the IC submodule is active, the three flags (IC1IF,
IC2QEIF and IC3DRIF) function as interrupt-on-capture
event flags for their respective input capture channels.
The channel must be configured for one of the events
that will generate an interrupt (see
Interrupts”
When the QEI is enabled, the IC1IF interrupt flag
indicates
measurement event, usually an update of the VELR
register. The IC2QEIF interrupt indicates that a position
measurement event has occurred. IC3DRIF indicates
that a direction change has been detected.

17.5.1
Since the input capture can operate only when its time
base is configured in a Synchronous mode, the input
capture will not capture any events. This is because the
device’s internal clock has been stopped and any inter-
nal timers in Synchronous modes will not increment.
The prescaler will continue to count the events (not
synchronized).
When the specified capture event occurs, the CAPx
interrupt will be set. The Capture Buffer register will be
updated upon wake-up from sleep to the current TMR5
value. If the CAPx interrupt is enabled, the device will
wake-up from Sleep. This effectively enables all input
capture channels to be used as the external interrupts.
