This has to be one for Hippy, Dippy or Technical I feel.
With the exception of the 28X1 and the 40X1 port A appears not to be used. Would I be out of order, fine by me, to ask for a quick potted history of why ports were numbered as they were. Excluding the straight numbers and the in.number and out.number variants, why do I get the impression that the sequence fills from C, B and then A?
Any chance of a little bit of the thinking behind the A, B and C or is that C, B and A or is the answer to view the Pic MicroChip documentation?
Alternatively if this has been covered before, a link to the thread would be good to go.
I really should go and paint the garden fence.
