Set GPIOx_PMD (PMDn[1:0]) to 00b the GPIOx port [n] pin is in Input mode and the I/O pin is in
tri-state (high impedance) without output drive capability. The GPIOx_PIN value reflects the status
of the corresponding port pins.
Set GPIOx_PMD (PMDn[1:0]) to 01b the GPIOx port [n] pin is in Output mode and the I/O pin
supports digital output function with source/sink current capability. The bit value in the
corresponding bit [n] of GPIOx_DOUT is driven on the pin.
