11.2.3.1 Input Capture
The 12-bit ATICR register is used to latch the val-
ue of the 12-bit free running upcounter after a ris-
ing or falling edge is detected on the ATIC pin.
When an input capture occurs, the ICF bit is set
and the ATICR register contains the value of the

free running upcounter. An IC interrupt is generat-
ed if the ICIE bit is set. The ICF bit is reset by read-
ing the ATICR register when the ICF bit is set. The
ATICR is a read only register and always contains
the free running upcounter value which corre-
sponds to the most recent input capture. Any fur-
ther input capture is inhibited while the ICF bit is
set.
