Names and Functions
Power supply

+3.3V power supply pin during normal operations and power saving
modes.

Port 0
:
Port 0 is an open-drain, bidirectional I/O port. Port 0 pins that have
1s written to them become floating 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:
An 8-bits 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. (See DC Electrical Characteristics: IIL).

：
PWM channel 1 output
P1.6 SCL

Reset
:
A high on this pin for two machine cycles while the oscillator is
running resets the device. An internal resistor to VSS permits a
power-on reset using only an external capacitor to VCC.
Port 2:
Port 2 is an 8-bits 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 DC Electrical Characteristics: IIL). Port 2
emits the high-order address byte during fetches from external
program memory and during accesses to external data memory that
uses 16-bits addresses (MOVX @DPTR). In this application, it uses
strong internal pull-ups when emitting 1s. During accesses to
external data memory that uses 8-bits addresses (MOV @Ri), port 2
emits the contents of the P2 special function register.

Port 3
:
Port 3 is an 8-bits 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 being pulled low will source current because of the
pull-ups. (See DC Electrical Characteristics: IIL). Port 3 also serves
the special features.
