This graph shows which files directly or indirectly include this file:

Macros
#define	CPUID_LEN (4U)
	Length of the CPU_ID in octets.

#define	PM_NUM_MODES (1U)
	Power mode configuration.

#define	PROVIDES_PM_LAYERED_OFF
	We provide our own pm_off() function for the native CPU.

#define	PERIPH_TIMER_PROVIDES_SET
	Prevent shared timer functions from being used.

#define	EEPROM_SIZE (1024U) /* 1kB */
	EEPROM configuration.

GPIO Configuration
#define	GPIO_PORT_SHIFT (24)
	The offset between Port and Pin.

#define	GPIO_PIN(port, pin)
	Define a custom GPIO_PIN macro for native.

#define	HAVE_GPIO_MODE_T
	Macro indicating whether GPIO modes are available on the native CPU.

#define	GPIOHANDLE_REQUEST_PULL_DOWN (0xFF)
	Pull-down.

#define	GPIOHANDLE_REQUEST_PULL_UP (0xFF)
	Pull-up.

#define	HAVE_GPIO_FLANK_T
	A macro indicating whether the native CPU supports GPIO edge behavior.

enum	gpio_mode_t { GPIO_IN = GPIOHANDLE_REQUEST_INPUT , GPIO_IN_PD = GPIOHANDLE_REQUEST_INPUT \| GPIOHANDLE_REQUEST_PULL_DOWN , GPIO_IN_PU = GPIOHANDLE_REQUEST_INPUT \| GPIOHANDLE_REQUEST_PULL_UP , GPIO_OUT = GPIOHANDLE_REQUEST_OUTPUT , GPIO_OD = GPIOHANDLE_REQUEST_OPEN_DRAIN , GPIO_OD_PU = GPIOHANDLE_REQUEST_OPEN_DRAIN \| GPIOHANDLE_REQUEST_PULL_UP }
	Available pin modes. More...

enum	gpio_flank_t { GPIO_FALLING = GPIOEVENT_EVENT_FALLING_EDGE , GPIO_RISING = GPIOEVENT_EVENT_RISING_EDGE , GPIO_BOTH = GPIO_FALLING \| GPIO_RISING }
	An enum for the type of flank that emit interrupts. More...

SPI Configuration
#define	PERIPH_SPI_NEEDS_TRANSFER_BYTE
	Use the common `transfer_byte` SPI function.

#define	PERIPH_SPI_NEEDS_TRANSFER_REG
	Use the common `transfer_reg` SPI function.

#define	PERIPH_SPI_NEEDS_TRANSFER_REGS
	Use the common `transfer_regs` SPI function.
