The Input Capture module is useful in applications that
requires frequency (period) and pulse measurement.
The dsPIC33FJ32MC302/304, dsPIC33FJ64MCX02/
X04 and dsPIC33FJ128MCX02/X04 devices support
up to four 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:

• Prescaler Capture Event modes:
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
