12F1840 - HPWM outputs PWM on CCP pin instead of P1B pin.

Hello.
I have PIC12F1840 configured to output PWM signal on P1B port (PORTA.4), according to APFCON register.

However, HPWM 1, 127, 20000 (as example)
outputs PWM signal on PORTA.2 pin.

I tried to configure APFCON register accordingly, but no luck.
I tried HPWM 2, HPWM 3 etc - no difference.
Hardware-wise everything is ok, since high/low, PWM PORTA.4 all work fine.

Here's my config.
What can be the reason?

Code:

I read somewhere that HPWM uses CCP pins (PBP manual?).

Yes it does, but when chip has multiple PWM output pins, usually HPWM 2, HPWM 3, etc, output on the corresponding pin.

you need to set the steering mode to drive p1b

Thanks, will try it a bit later!

This fixed it, thanks again!
