    PortA.4 is not responding though....it stays low
    for PORTA.4... well... it's an open-collector output type on this one. So you may need to slightly modify your hardware and software.

    In brief, connect your LED between Vdd and PORTA.4, and change those
    Code:
    PORTA = 0
    to
    Code:
    PORTA = %00010000
    That should work for LEDs. If you drive a transistor but then it's easier... not software modification are needed, just hardware.

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.
