The Input Capture module is useful in applications
requiring frequency (period) and pulse measurement.
The PIC32MX3XX/4XX devices support up to five input
capture channels.
The Input Capture module captures the 16-bit or 32-bit
value of the selected Time Base registers when an
event occurs at the ICx pin. The events that cause a
capture event are listed below in three categories:
1.

Each input capture channel can select between one of
two 16-bit timers (Timer2 or Timer3) for the time base,
or two 16-bit timers (Timer2 and Timer3) together to
form a 32-bit timer. 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
• Input capture can also be used to provide
