I/O with
internal
pull-up
Port 1: Port 1 is an 8-bit bidirectional I/O port with internal pull-ups. The
Port 1 pins are pulled HIGH by the internal pull-ups when 1s are written to
them and can be used as inputs in this state. As inputs, Port 1 pins that are
externally pulled LOW will source current (IIL) because of the internal
pull-ups. P1[5], P1[6], P1[7] have high current drive of 16 mA.

I/O with
internal
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 1s 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 1s.
