In Single Output mode, pulse steering allows any of the
PWM pins to be the modulated signal. Additionally, the
same PWM signal can be simultaneously available on
multiple pins.
Once
(CCP1M<3:2> = 11
CCP1CON register), the user firmware can bring out
the same PWM signal to one, two, three or four output
pins by setting the appropriate STR<D:A> bits of the
PSTRCON register, as shown in

The PWM Steering mode is available only when the CCP1CON register bits CCP1M<3:2> = 11 and
P1M<1:0> = 00.

While the PWM Steering mode is active, CCP1M<1:0>
bits of the CCP1CON register select the PWM output
polarity for the P1<D:A> pins.
The PWM auto-shutdown operation also applies to
PWM Steering mode as described in
“Enhanced
auto-shutdown event will only affect pins that have
PWM outputs enabled.
Note:
The associated TRIS bits must be set to
output (‘0’) to enable the pin output driver
in order to see the PWM signal on the pin.
