12.0
Devices in the PIC24FJ256GB110 family all feature
9 independent input capture modules. Each of the
modules offers a wide range of configuration and oper-
ating options for capturing external pulse events and
generating interrupts.
Key features of the input capture 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
(Register 12-2). A general block diagram of the module
is shown in Figure 12-1.

By default, the input capture module operates 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>).
