    I have it working with this code:
    DEFINE OSC 4
    CMCON=%00000111
    VRCON = 0
    PAUSEus 10
    TRISA = %00000110
    TRISB = %11110001
    PORTA = %00000000
    PORTB = %00000000
    OPTION_REG.7 = 0
    OPTION_REG.6 = 0
    rf var porta.4

    main:
    low rf
    pause 500
    high rf
    pause 500
    goto main

    Does it have something to do with me using the comparator on ra.1,ra.2? I have been reading the datasheet and it mentions ra.3,ra.4 in section5.1 PORTA and TRISA Registers, I am already using ra.3 with no problems as an output.
