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 ‘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 making the
transition to ‘1’s.
