0x0: Analog, input or output (GPIO_PxIN always reads 1).
0x1: Output, push-pull (GPIO_PxOUT controls the output).
0x4: Input, floating.
0x5: Output, open-drain (GPIO_PxOUT controls the output).
0x8: Input, pulled up or down (selected by GPIO_PxOUT: 0 = pull-down, 1 = pull-up).
0x9: Alternate output, push-pull (peripheral controls the output).
0xB: Alternate output SPI SCLK, push-pull (only for SPI master mode SCLK).
0xD: Alternate output, open-drain (peripheral controls the output).
