Input Capture (ICU)
The input capture (ICU) generates an interrupt request to the CPU simultaneously with a storing operation of
current counter value of the 24-bit free run timer to the ICU data register (ICDR) upon an input of a trigger edge
to the external pin.
There are four sets (four channels) of the input capture external pins and ICU data registers (ICDR), enabling
measurements of maximum of four events.
The input capture has four sets of external input pins (ASR0 to ASR3) and ICU registers (ICDR), enabling
measurements of maximum of four events.
A trigger edge direction can be selected from rising/falling/both edges.
The input capture can be set to generate an interrupt request at the storage timing of the counter value of the
24-bit free run timer to the ICU data register (ICDR).
The input compare conforms to the extended intelligent I/O service (EI2OS).
The input capture function is suited for measurements of intervals (frequencies) and pulse-widths.
