REGISTER 17-3:
17.5.7
In Single Output mode, pulse steering allows any of the
PWM pins to be the modulated signal. Additionally, the
same PWM signal can simultaneously be available on
multiple pins.
Once
(CCPxM<3:2> = 11 and PxM<1:0> = 00 of the
CCPxCON 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
PSTRxCON register, as provided in Table 17-4.

While the PWM Steering mode is active, the
CCPxM<1:0> bits of the CCPxCON register select the
PWM output polarity for the Px<D:A> pins.
The PWM auto-shutdown operation also applies to
PWM Steering mode as described in Section 17.5.4
“Enhanced

PWM outputs enabled.
