In Single Output mode, PWM 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
(CCPxM<3:2> = 11
CCPxCON register), the user firmware can bring out
the same PWM signal to one, two, three or four output
pins by setting the appropriate Steering Enable bits
(STRxA, STRxB, STRxC and/or STRxD) of the
PSTRxCON register, as shown in
While the PWM Steering mode is active, CCPxM<1:0>
bits of the CCPxCON register select the PWM output
polarity for the PxD, PxC, PxB and PxA pins.
The PWM auto-shutdown operation also applies to
PWM Steering mode as described in
“Enhanced PWM Auto-shutdown
shutdown event will only affect pins that have PWM
outputs enabled.

The STRxSYNC bit of the PSTRxCON register gives
the user two selections of when the steering event will
happen. When the STRxSYNC bit is ‘0’, the steering
event will happen at the end of the instruction that
writes to the PSTRxCON register. In this case, the
output signal at the PxA, PxB, PxC and PxD pins may
be an incomplete PWM waveform. This operation is
useful when the user firmware needs to immediately
remove a PWM signal from the pin.
When the STRxSYNC bit is ‘1’, the effective steering
update will happen at the beginning of the next PWM
period. In this case, steering on/off the PWM output will
always produce a complete PWM waveform.
