24.4.1
In Half-Bridge mode, two pins are used as outputs to
drive push-pull loads. The PWM output signal is output
on the CCPx/PxA pin, while the complementary PWM
output signal is output on the PxB pin (see
This mode can be used for Half-Bridge applications, as
shown in
where four power switches are being modulated with
two PWM signals.
In Half-Bridge mode, the programmable dead-band delay
can be used to prevent shoot-through current in Half-
Bridge power devices. The value of the PDC<6:0> bits of
the PWMxCON register sets the number of instruction
cycles before the output is driven active. If the value is
greater than the duty cycle, the corresponding output
remains

Since the PxA and PxB outputs are multiplexed with the
PORT data latches, the associated TRIS bits must be
cleared to configure PxA and PxB as outputs.
