This section describes the output compare module and
associated operational modes. The features provided
by this module are useful in applications requiring
operational modes, such as:
• Generation of Variable Width Output Pulses
• Power Factor Correction
Figure 13-1 depicts a block diagram of the output
compare module.

peripherals, register descriptions and general device
functionality, refer to the dsPIC30F Family Reference
Manual (DS70046). For more information on the device

The key operational features of the output compare
module include:
• Timer2 and Timer3 Selection mode
• Simple Output Compare Match mode
• Dual Output Compare Match mode
• Simple PWM mode
• Output Compare during Sleep and Idle modes
• Interrupt on Output Compare/PWM Event
These operating modes are determined by setting the
appropriate bits in the 16-bit OCxCON SFR (where x = 1,
2, 3, ..., N). The dsPIC30F4011/4012 devices have
4/2 compare channels, respectively.
OCxRS and OCxR in the figure represent the Dual
Compare registers. In the Dual Compare mode, the
OCxR register is used for the first compare and OCxRS
is used for the second compare.
