The Input Capture module is useful in applications
requiring frequency (period) and pulse measurement.
The PIC24HJ12GP201/202 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

Note: An ‘x’ in a signal, register or bit name denotes the number of the capture channel.

• 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
