STDIO configuration
As the CPU is too slow to handle 115200 baud, we set the default baudrate to 9600 for this board
#define	STDIO_UART_BAUDRATE (9600U)

xtimer configuration values
#define	XTIMER_WIDTH (16)

#define	XTIMER_HZ (CLOCK_CORECLOCK / 8)

#define	XTIMER_BACKOFF (40)

Macros for controlling the on-board LED
#define	LED0_PIN GPIO_PIN(PORT_B, 5)

#define	LED0_MODE GPIO_OUT

#define	LED0_ENABLE_PORT DDRB \|= LED0_PIN

#define	LED0_ON PORTB \|= LED0_PIN

#define	LED0_OFF PORTB &= ~LED0_PIN

#define	LED0_TOGGLE PORTB ^= LED0_PIN

Button pin configuration
#define	BTN0_PIN GPIO_PIN(PORT_B, 7)

#define	BTN0_MODE GPIO_IN_PU

#define	BTN0_INT_FLANK GPIO_FALLING
