I/O with

pull-up
Port 2: Port 2 is an 8-bit bidirectional I/O port with internal
pull-ups. Port 2 pins are pulled HIGH by the internal
pull-ups when ‘1’s are written to them and can be used as
inputs in this state. As inputs, Port 2 pins that are
externally pulled LOW will source current (IIL) because of
the internal pull-ups. Port 2 sends the high-order address
byte during fetches from external program memory and
during accesses to external Data Memory that use 16-bit
address (MOVX@DPTR). In this application, it uses strong
internal pull-ups when transitioning to ‘1’s.
