Pin Description(continued)
Port 1 : PIN 1~8 (DIP40), PIN 2~9 (PLCC44)
Port 1 is an 8-bit bi-directional I/O port with internal pullups.
Port 1 pins that have 1's written to them are pulled high by the internal pullups,
and in that state can be used as inputs. As inputs, Port 1 pins that are externally
being pulled low will source current because of the internal pullups.
Port 2 : PIN 21~28 (DIP40), PIN 24~31 (PLCC44)
Port 2 is an 8-bit bi-directional I/O port with internal pullups. Port 2 pins that have
1's written to them are pulled high by the internal pullups, and in that state can
be used as inputs. As inputs, Port 2 pins that are externally being pulled low will
source current because of the internal pullups.
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 pullups when emitting
1's. During accesses to
external data memory that use 8-bit addresses (MOVX @
Ri), Port 2 emits the contents of the P2 Special Function Register
Port 3 : PIN 10~17 (DIP40), PIN 13~19 (PLCC44)
Port 3 is an 8-bit bi-directional I/O port with internal pullups. Port 3 pins that have
1's written to them are pulled high by the internal pullups, and in that state can
be used as inputs. As inputs, Port 3 pins that are externally being pulled low will
source current because of the pullups.
Port 3 also serves the function of various special feature of the MCS-51 Family, as
listed below :

T0 (Timer 0 external input)
T1 (Timer 1 external input)
WR (external data memory write strobe)
RD (external data memory read strobe)
RST : PIN 9 (DIP40), PIN 10 (PLCC44)
Reset input. A high on this pin for two machine cycles while the oscillator is
running resets the device. An internal diffused resistor to V
SS
permits Power-On
reset using only an external capacitor to V
CC
