(2) Input Capture (ICU)
The input capture (ICU) consists of a capture register corresponding to two 16-bit external input pins, a control
register, and an edge detector. Upon input of a trigger edge through an external input pin, the counter value of
the 16-bit free-run timer is stored into the input capture register, and an interrupt request can be generated
concurrently.
A capture interrupt can be generated independently for each capture unit.
The extended intelligent I/O service (EI
2
OS) can be activated.
A trigger edge direction can be selected from rising/falling/both edges.
Since two input capture units can be operated independent of each other, up to two events can be measured
independently.
The input capture function is suited for measurements of intervals (frequencies) and pulse-widths.
