I have this working well on PIC16F887 but now I am trying to run it
on PIC18F67J60  (PIC-MICRO-WEB).

I am using TMR2 interrupt to update the CCP4 module.

PR2 =3D255
PR4 =3D 99

Debugging appears to shows that the duty cycle is dependant on CCPR4L and
PR2.

The manual implies PR4 and CCPR4L determine the duty cycle.

If I set PR2 to 99 and CCPR4L to 100 i get full power but TMR2 interrupts
too often. PR4 seems to have nil effect.

As always I am clearly doing something wrong but I am baffled

Currently lost 2 of the 3 phases (40+ degree day so lots of aircons running
in the hood) so debugging has ground to a halt.
