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

The BREAK pin value is latched by the BA bit.
