-/**
- * \brief Set the pad function of a group of pins
- *
- * Multiplex a group of pins to the same pad function. This is useful for
- * peripherals that use the same function number for several pins. This function
- * allows those pins to be set with a single call.
- *
- * Example:
- *	gpio_set_multipin_func(GPB, (1 << 23) | (1 << 22), 2);
- *
- * @param[in] port GPIO port of the pin (GPA -> GPS)
- * @param[in] pin_mask 32-bit mask indicating which pins to re-multiplex. For
- *			each set bit, the corresponding pin will be multiplexed.
- * @param[in] pad_func The peripheral function to which to connect the pins
