Figure 46. Input capture timing diagram
Long range input capture
Pulses that last more than 8 µs can be measured with an accuracy of 4 µs if f
MHz in the following conditions:

This configuration allows to cascade the Lite timer and the 12-bit AT4 timer to get a 20-bit
input capture value. Refer to

The 12-bit AT4 timer is clocked by the Lite timer (RTC pulse: CK[1:0] = 01 in the ATCSR
register)
The ICS bit in the ATCSR2 register is set so that the LTIC pin is used to trigger the AT4
timer capture.
The signal to be captured is connected to LTIC pin
Input Capture registers LTICR, ATICRH and ATICRL are read
