Parameter: port represents the number of the GPIO, 1 or 2
Mode 8 bit of a bit, each bit controls the input and output mode of a GPIO pin,
Bit =1, the corresponding pin is used as the input port.
Bit =0, the corresponding pin is used as an output port.
Return value Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0
GPIO pin PIN8 PIN7 PIN6 PIN5 PIN4 PIN3 PIN2 PIN1
Note: The output value is valid only when the pin is in output mode.
