Section 10 Advanced Timer Unit (ATU)
Input Capture Operation when Free-Running Counter is Halted: In channel 0 or channels 1
to 5, if input capture setting is performed and a trigger signal is input from the input pin, the
TCNT value will be transferred to the corresponding general register (GR) or input capture
register (ICR) irrespective of whether the free-running counter (TCNT) is running or halted, and
the IMF or ICF bit will be set in the timer status register (TSR).
The timing in this case is shown in figure 10.62
