I/O
Port 0:
Port 0 is an open drain, bidirectional I/O port. Port 0 pins that have 1s
written to them float and can be used as high-impedance inputs. Port 0 is also
the multiplexed low-order address and data bus during accesses to external
program and data memory. In this application, it uses strong internal pull-ups
when emitting 1s.
Port 1:
Port 1 is an 8-bit bidirectional I/O port with internal pull-ups on all pins.
Port 1 pins that have 1s written to them are pulled HIGH by the internal pull-ups
and can be used as inputs. As inputs, Port 1 pins that are externally pulled LOW
will source current because of the internal pull-ups.

Port 2:
Port 2 is a 8-bit bidirectional I/O port with internal pull-ups. Port 2 pins
that have 1s written to them are pulled HIGH by the internal pull-ups and can be
used as inputs. As inputs, port 2 pins that are externally being pulled LOW will
source current because of the internal pull-ups. (See
Section 9 “Static
characteristics”
, I
IL
). Port 2 emits the high-order address byte during fetches from
external program memory and during accesses to external data memory that
use 16-bit addresses (MOVX @ DPTR) or 23-bit addresses (MOVX @EPTR,
EMOV). In this application, it uses strong internal pull-ups when emitting 1s.
During accesses to external data memory that use 8-bit addresses (MOV @ Ri),
port 2 emits the contents of the P2 Special Function Register.
Note that when 23-bit address is used, address bits A16-A22 will be outputted to
P2.0-P2.6 when ALE is HIGH, and address bits A8-A14 are outputted to
P2.0-P2.6 when ALE is LOW. Address bit A15 is outputted on P2.7 regardless of
ALE.
