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 pins must
be polarized to Vcc or Vss in order to prevent any parasitic current consumption.
Port 0 is also the multiplexed low-order address and data bus during access to
external program and data memory. In this application, it uses strong internal
pull-up when emitting 1s. Port 0 also inputs the code bytes during EPROM
programming. External pull-ups are required during program verification during
which P0 outputs the code bytes.

I/O
Port 1:
Port 1 is an 8-bit bidirectional I/O port with internal pull-ups. 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 1 also receives the low-order
address byte during memory programming and verification.

I/O
Port 2
: Port 2 is an 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 pulled low will
source current because of the internal pull-ups. 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).In this application, it
uses strong internal pull-ups emitting 1s. During accesses to external data memory
that use 8-bit addresses (MOVX @Ri), port 2 emits the contents of the P2 SFR.
Some Port 2 pins (P2.0 to P2.5) receive the high order address bits during
EPROM programming and verification:
P3.0-P3.7

I/O
Port 3:
Port 3 is an 8-bit bidirectional I/O port with internal pull-ups. Port 3
pins that have 1s written to them are pulled high by the internal pull-ups and
can be used as inputs. As inputs, Port 3 pins that are externally pulled low will
source current because of the internal pull-ups. Some Port 3 pins (P3.4 to P3.5)
receive the high order address bits during EPROM programming and verification.
Port 3 also serves the special features of the 80C51 family, as listed below.
