/**
 * @ingroup     boards_esp32c6_devkit
 * @brief       Board definitions for ESP32-C6-DevKit boards
 * @{
 *
 * The board definitions in this file are valid for Espressif
 * ESP32-C6-DevKitx boards that use one of the following modules:
 *
 * - ESP32-C6-MINI-1x module (ESP32-C6-DevKitM-1 board)
 * - ESP32-C6-WROOM-1x module (ESP32-C6-DevKitC-1 board)
 *
 * Since the number of GPIOs and their possible uses on the ESP32-C6 are quite
 * limited, these board definitions can also be used for most other
 * ESP32-C6 boards. Any modifications required for specific applications
 * can be overridden by \ref esp32_application_specific_configurations
 * "application-specific board configuration".

 * ESP32-C6-DevKit boards have a BOOT button connected to GPIO9, which can be
 * used as button during normal operation. Since the GPIO9 pin is pulled up,
 * the button signal is inverted, i.e., pressing the button will give a
 * low signal.

 * @brief   Default button GPIO mode definition

 * Since the GPIO pin of the button needs to be pulled up for normal operation

 * the mode for the GPIO pin must be set to GPIO_IN_PU.
