The input capture module is useful in applications
requiring frequency (period) and pulse measurement.
The PIC24HJ32GP202/204 and PIC24HJ16GP304
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:

• Simple Capture Event modes:
• Capture timer value on every edge (rising and
• Prescaler Capture Event modes:
Each input capture channel can select one of the
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
• Four-word FIFO buffer for capture values
• Use of input capture to provide additional sources
