18F4620 HPWM Half Bridge Mod problem

[Bruce]

HPWM is intended for standard CCP PWM modules. It does not work for enhanced PWM
modules. You'll need to set things up manually.

I don't have an 18F4620 to test this with, but see if this doesn't work;

DEFINE	OSC 20

Duty VAR WORD ' 5%=25, 95%=450

TRISC.2=0
TRISD.5=0

T2CON = %00000101  ' Timer2 ON, prescale 1:4
PR2 = 124          ' 10kHz
CCP1CON = %10001100' half-bridge with P1A & P1B

Loop:
  For Duty = 25 TO 450  ' from 5% to 95% duty
   CCP1CON.4 = Duty.0	' Setup 10-bit duty cycle as
   CCP1CON.5 = Duty.1	' a 10-bit word
   CCPR1L = Duty >> 2
   PAUSE 250
  Next
  Goto loop
	
  End
