I/O PORTS

I/O pin allocation of ports for the different package types

is designed to provide configuration flexibility. Each port

line of Ports 0, 1, and 2 can be independently selected as

an input or an output. Each port’s output lines can be glo-

bally selected as push-pull or as open-drain outputs
