Detailed Description

Shared files and configuration for Arduino Atmega boards.

Files
file	arduino_iomap.h
	Mapping from MCU pins to Arduino pins for Arduino Atmega boards.

file	board_common.h
	Common board configuration for Arduino Atmega boards.

file	gpio_params.h
	Common configuration of mapped GPIOs for Arduino Atmega boards.

file	periph_conf.h

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)

Usage of LED to turn on when a kernel panic occurs.
#define	LED_PANIC LED0_ON

CPU clock scale for arduino boards
#define	CPU_ATMEGA_CLK_SCALE_INIT CPU_ATMEGA_CLK_SCALE_DIV1

xtimer configuration values
#define	XTIMER_WIDTH (16)

#define	XTIMER_HZ (250000UL)

#define	XTIMER_BACKOFF (40)

ztimer configuration values
#define	CONFIG_ZTIMER_USEC_TYPE ZTIMER_TYPE_PERIPH_TIMER

#define	CONFIG_ZTIMER_USEC_DEV (TIMER_DEV(0))

#define	CONFIG_ZTIMER_USEC_FREQ (250000LU)

#define	CONFIG_ZTIMER_USEC_WIDTH (16)
