19.4.1
In Half-Bridge mode, two pins are used as outputs to
drive push-pull loads. The PWM output signal is output
on the PxA pin, while the complementary PWM output
signal is output on the PxB pin (see Figure 19-6). This
mode can be used for half-bridge applications, as
shown in Figure 19-7, or for full-bridge applications,
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 PxDC<6:0>
bits of the ECCPxDEL 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 inactive during the entire cycle. For more
details on the dead-band delay operations, see
Section 19.4.6 “Programmable Dead-Band Delay
Mode”.

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.
