void gpio_set_af | ( | uint32_t | gpioport, |

Set GPIO Alternate Function Selection.
Set the alternate function mapping number for each pin. Most pins have alternate functions associated with them. When set to AF mode, a pin may be used for one of its allocated alternate functions selected by the number given here. To determine the number to be used for the desired function refer to the individual datasheet for the particular device. A table is given under the Pin Selection chapter.
Note that a number of pins may be set but only with a single AF number. In practice this would rarely be useful as each pin is likely to require a different number.
