24.4.6 PWM STEERING MODE

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 the Single Output mode is selected

(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 STRx<D:A> bits of the

PSTRxCON register, as shown in Table 24-9.

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.

While the PWM Steering mode is active, 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 24.4.3

“Enhanced PWM Auto-shutdown mode”. An auto-

shutdown event will only affect pins that have PWM

outputs enabled.

2:

Port outputs are configured as shown when

the CCPxCON register bits PxM<1:0> = 00

and CCPxM<3:2> = 11.

Single PWM output requires setting at least

one of the STRx bits.
