The input capture module is useful in applications
requiring frequency (period) and pulse measurement.
The
support up to eight input capture channels.
The input capture module captures the 16-bit value of
the selected Time Base register when an event occurs
at the ICx pin. The events that cause a capture event
are listed below in three categories:

Each input capture channel can select between one of
two 16-bit timers (Timer2 or Timer3) for the time base.
The selected timer can use either an internal or exter-
nal clock.
Other operational features include the following:
• Device wake-up from capture pin during CPU
• Interrupt on input capture event
• 4-word FIFO buffer for capture values
• Input capture can also be used to provide
Sleep and Idle modes
- Interrupt optionally generated after 1, 2, 3 or
additional sources of external interrupts
Note:
- Capture timer value on every rising edge of
Capture timer value on every edge (rising and
falling) of input at ICx pin

- Capture timer value on every 4th rising edge
- Capture timer value on every 16th rising edge

Only IC1 and IC2 can trigger a DMA data
transfer. If DMA data transfers are
required, the FIFO buffer size must be set
to ‘1’ (ICI<1:0> = 00).
