Macros

#define GPIO_DT_FLAGS_MASK   0x3F
 Mask for DT GPIO flags.
 
#define GPIO_INT_WAKEUP   (1 << 6)
 Configures GPIO interrupt to wakeup the system from low power mode.
 
GPIO pin active level flags
#define GPIO_ACTIVE_LOW   (1 << 0)
 GPIO pin is active (has logical value '1') in low state.
 
#define GPIO_ACTIVE_HIGH   (0 << 0)
 GPIO pin is active (has logical value '1') in high state.
 
GPIO pin drive flags
#define GPIO_OPEN_DRAIN   (GPIO_SINGLE_ENDED | GPIO_LINE_OPEN_DRAIN)
 Configures GPIO output in open drain mode (wired AND).
 
#define GPIO_OPEN_SOURCE   (GPIO_SINGLE_ENDED | GPIO_LINE_OPEN_SOURCE)
