NOTE(S):
1. I/O Types:
I = Standard input
I^{P =} Input with internal pull-up resister
O = Standard output
O^D = Output with open drain
2. Legend:
[#] = Port number
(#) = Bit number
To insure 5 V tolerance in mixed + 5 V / + 3.3 V systems, this input must
be connected to + 5 V. If all logic input signals are 3.3 V levels, then this
pin may be connected to the 3.3 V supply.
No-connect pins are reserved for future device compatibility and should
be left unconnected.
