Devices in the PIC24FJ256GA110 family all feature
9 independent enhanced input capture modules. Each
of the modules offers a wide range of configuration and
operating options for capturing external pulse events
and generating interrupts.
Key features of the enhanced output module include:
• Hardware-configurable for 32-bit operation in all
• Synchronous and Trigger modes of output
• A 4-level FIFO buffer for capturing and holding
• Configurable interrupt generation
• Up to 6 clock sources available for each module,
The module is controlled through two registers: ICxCON1

By default, the enhanced input capture module oper-
ates in a free-running mode. The internal 16-bit counter
ICxTMR counts up continuously, wrapping around from
FFFFh to 0000h on each overflow, with its period
synchronized to the selected external clock source.
When a capture event occurs, the current 16-bit value
of the internal counter is written to the FIFO buffer.
In Synchronous mode, the module begins capturing
events on the ICx pin as soon as its selected clock
source is enabled. Whenever an event occurs on the
selected sync source, the internal counter is reset. In
Trigger mode, the module waits for a Sync event from
another internal module to occur before allowing the
internal counter to run.
Standard, free-running operation is selected by setting
the SYNCSEL bits to ‘00000’ and clearing the ICTRIG
bit (ICxCON2<7>). Synchronous and Trigger modes
are selected any time the SYNCSEL bits are set to any
value except ‘00000’. The ICTRIG bit selects either
Synchronous or Trigger mode; setting the bit selects
Trigger mode operation. In both modes, the SYNCSEL
bits determine the sync/trigger source.
When the SYNCSEL bits are set to ‘00000’ and
ICTRIG is set, the module operates in Software Trigger
mode. In this case, capture operations are started by
manually setting the TRIGSTAT bit (ICxCON2<6>).
