Input capture mode
The 12-bit ATICR register is used to latch the value of the 12-bit free running upcounter
CNTR1 after 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 generated 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.
