- * Abstract:
- *         This file contains gpio pin configuration functions.
- *      Some additional function for setting and getting pin values, getting
- *      descriptors etc. are defined in header file as inline functions.
- *
- *      Each pin is defined by its descriptor defined in hal_gpio_platform_def. The descriptor can be obtained
- *      by hal_gpio_get_pin_dsc by giving a pin name as an argument.
