Benjamin Valentin	93d2068a9e	cpu/atmega_common: Implement RTC based on TIM2 ... This implements a basic Real Time Clock based on TIM2. As the timer is too fast and wraps around after just 8 bits, it is not used directly. Instead TIM2 is responsible for providing a 1 Hz tick by generating an alarm every second. The current time data is kept in the `.noinit` section, so it will survive a reboot, but the clock will not be updated while the bootloader runs, so expect inaccuracies.	2020-03-03 16:26:26 +01:00
