Macros
#define	CLOCK_CORECLOCK GHZ(1)

Timer peripheral configuration
#define	TIMER_NUMOF (1U)

#define	TIMER_CHANNEL_NUMOF (1U)
	Number of timer channels.

<tt>xtimer</tt> configuration
timer_set_absolute has a high margin for possible underflow if set with value not far in the future. To prevent this, we set high backoff values here.

#define	XTIMER_ISR_BACKOFF 200

SPI configuration (Linux host only)
#define	SPI_NUMOF (1U)
	Amount of SPI devices.

#define	SPI_MAXCS (4U)
	Maximum amount of chip select lines per bus.

#define	SPI_HWCS(x)
	Hardware chip select access macro.
