3 *parameter description:
Parameter:port fill in subcard GPIO number, 1or 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.
Note: The
output value is
valid only when the pinis in output mode.
