11.2.3.5 Input Capture Mode
The 12-bit ATICR register is used to latch the val-
ue of the 12-bit free running upcounter CNTR1 af-
ter a rising 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 gen-
erated if the ICIE bit is set. The ICF bit is reset by

reading the ATICRH/ATICRL register when the
ICF bit is set. The ATICR is a read only register
and always contains the free running upcounter
value which corresponds to the most recent input
capture. Any further input capture is inhibited while
the ICF bit is set.
