Re: using all port pins
You might be better off using the TTL serial port. If that's not an option, many PICs have a parallel port - I don't know if the pins that it uses are wired out to the front of the RC, but if they are you could use that to shift entire bytes in and out.
Failing that you can always just use the digital ins, shift and add. Something along the lines of IN_1 << 7 + IN_2 << 6 + IN_3 << 5 etc.
