The subtle problem of being able to set the state of a OUTPUT
pin by noise which may occur during a Read/Modify/Write to another
pin in the same port, is worth emphasising again (periodically)
so any 'newbies' don't get 'bit' by it as many of us have at
OUR time. I notice one (at least, ...) 'unmentionable' <G.>chipmaker
now adds another register to the port logic to try to avoid this.

Maybe we could all stop politic-ing long enough to but together
a 'gotchas' list. We could co-locate it with the PICList Archive.
