15.0
All devices in the PIC24FV32KA304 family feature
3 independent output compare modules. Each of these
modules offers a wide range of configuration and
operating options for generating pulse trains on internal
device events. Also, the modules can produce
Pulse-Width Modulated (PWM) waveforms for driving
power applications.
Key features of the output compare module include:
• Hardware-configurable for 32-bit operation in all
• Synchronous and Trigger modes of output
• Two separate Period registers (a main register,
• Configurable for single pulse or continuous pulse
• Up to 6 clock sources available for each module,

15.1.1
By default, the output compare module operates in a
free-running mode. The internal 16-bit counter,
OCxTMR, counts up continuously, wrapping around
from FFFFh to 0000h on each overflow, with its period
synchronized to the selected external clock source.
Compare or PWM events are generated each time a
match between the internal counter and one of the
Period registers occurs.

PIC24FV32KA304 FAMILY
In Synchronous mode, the module begins performing
its compare or PWM operation as soon as its selected
clock source is enabled. Whenever an event occurs on
the selected sync source, the module’s internal counter
is reset. In Trigger mode, the module waits for a sync
event from another internal module to occur before
allowing the counter to run.
Free-running mode is selected by default, or any time
that the SYNCSEL bits (OCxCON2<4:0>) are set to
‘00000’. Synchronous or Trigger modes are selected
any time the SYNCSEL bits are set to any value except
‘00000’. The OCTRIG bit (OCxCON2<7>) selects
either Synchronous or Trigger mode. Setting this bit
selects Trigger mode operation. In both modes, the
SYNCSEL bits determine the sync/trigger source.
15.1.2
By default, each module operates independently with
its own set of 16-bit Timer and Duty Cycle registers. To
increase the range, adjacent even and odd modules
can be configured to function as a single 32-bit module.
(For example, Modules 1 and 2 are paired, as are
Modules 3 and 4, and so on.) The odd-numbered
module (OCx) provides the Least Significant 16 bits of
the 32-bit register pairs, and the even-numbered
module (OCy) provides the Most Significant 16 bits.
Wrap arounds of the OCx registers cause an increment
of their corresponding OCy registers.
Cascaded operation is configured in hardware by setting
the OC32 bit (OCxCON2<8>) for both modules.
