    Talking Rtfds ....

    from the Midrange Databook $30.5

    Code:
    Example Absolute Maximum Ratings†
    Ambient temperature under bias........................................................................... . -55 to +125°C
    Storage temperature .......................................................................................... -65°C to +150°C
    Voltage on any pin with respect to VSS (except VDD, MCLR, and RA4)..... -0.3V to (VDD + 0.3V)
    Voltage on VDD with respect to VSS ....................................................................... -0.3 to +7.5V
    Voltage on MCLR with respect to VSS (2) ...................................................................... 0 to +14V
    Voltage on RA4 with respect to Vss .............................................................................. 0 to +14V
    Total power dissipation (1) .................................................................................................... 1.0W
    Maximum current out of VSS pin ...................................................................................... 300 mA
    Maximum current into VDD pin ......................................................................................... 250 mA
    Input clamp current, IIK (VI < 0 or VI > VDD).................................................................... ± 20 mA
    Output clamp current, IOK (VO < 0 or VO > VDD) ............................................................. ± 20 mA
    Maximum output current sunk by any I/O pin..................................................................... 25 mA
    Maximum output current sourced by any I/O pin ............................................................... 25 mA
    Maximum current sunk by PORTA, PORTB, and PORTE (combined)............................. 200 mA
    Maximum current sourced by PORTA, PORTB, and PORTE (combined) ....................... 200 mA
    Maximum current sunk by PORTC and PORTD (combined) ........................................... 200 mA
    Maximum current sourced by PORTC and PORTD (combined)...................................... 200 mA
    Maximum current sourced by PORTC and PORTD (combined)...................................... 200 mA
    Maximum current sourced by PORTF and PORTG (combined) ...................................... 100 mA
    Maximum current sourced by PORTF and PORTG (combined) ...................................... 100 mA
    just need to be read ...

    ALSO WRITTEN: SEE PARTICULAR DATASHEETS ...

    Means parallelling outputs ( or inputs ... why not ? ) is allowed ... You're right, Steve !!!

    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!
