Was playing with 18F4431 this cold weekend, few things still not clear:

- PWM mode works just fine, using 12 bits,
but if I am trying to read PTMRH - reading always 0, PTMRL - no problem - changing fast

- Encoder input - not working at all I just need aimple counter with A/B signals:
Here what I have:
Code:
  MOVLW B'11111111' 
  MOVWF TRISA, 0
  MOVLW B'00000100' 
  MOVWF QEICON, 0
  MOVLW B'11111111' 
  MOVWF MAXCNTL, 0
  MOVLW B'00000011' 
  MOVWF MAXCNTH, 0
Reading POSCNTH, POSCNTL - nothing always 0, if I write something to pos counter, I see these values

Any ideas?
Thanks
