The input capture module is useful in applications
requiring frequency (period) and pulse measurement.
The dsPIC33FJ32MC202/204 and dsPIC33FJ16MC304
devices 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 one of two
16-bit timers (Timer2 or Timer3) for the time base.
The selected timer can use either an internal or
external clock.
Other operational features include:
• Device wake-up from capture pin during CPU
• Interrupt on input capture event
• 4-word FIFO buffer for capture values
• Use of input capture to provide additional sources
- Capture timer value on every falling edge of
- Capture timer value on every rising edge of
- Capture timer value on every 4th rising edge
- Capture timer value on every 16th rising
Sleep and Idle modes
- Interrupt optionally generated after 1, 2, 3 or
of external interrupts
