Input Capture
Event Source Selection for capture operation
The Event Action setting in the Timer/Counter will determine the type of capture that is done.
The CC channel to use must be enabled individually before capture can be done. When the cap-
ture condition occur, the Timer/Counter will time-stamp the event by copying the current value in
the Count register into the enabled CC channel register.
When an I/O pin is used as event source for the Capture, the pin must be configured for edge
sensing. For details on sense configuration on I/O pins, refer to
page
will be stored in the Most Significant Bit (MSB) of the Capture register after a Capture. If the
MSB of the Capture register is zero, a falling edge generated the Capture. If the MSB is one, a
rising edge generated the Capture.
Three different types of capture are available.
Selecting the input capture event action, makes the enabled capture channel perform an input
capture on any event. The interrupt flags will be set and indicate that there is a valid capture
result in the corresponding CC register. Equally the buffer valid flags indicates valid data in the
buffer registers. Refer to
buffering.
The counter will continuously count for BOTTOM to TOP, then restart on BOTTOM as shown in
