    __CONFIG _CONFIG3H, _CCP2MX_OFF_3H puts ccp2 onto portb.3
    use

    DEFINE CCP2_REG PORTB 'Channel-2 port
    DEFINE CCP2_BIT 3 'Channel-2 bit

    or
    __CONFIG _CONFIG3H, _CCP2MX_ON_3H


    or set trisb.3 to 0 and trisc.2 to 0 and CCP2CON=12



    from data sheet
    bit 0 CCP2MX: CCP2 Mux bit
    1 = CCP2 input/output is multiplexed with RC1
    0 = CCP2 input/output is multiplexed with RB3
