Watch crystal usage for RTC #6

Closed gaborsimon closed 8 years ago

gaborsimon commented 8 years ago

ATmega16 contains a timer modul (Timer2) that can be used for RTC functionality. Currently 16-bit Timer1 modul is used to generate 1sec interrupt. This timer modul runs from f_io that is the internal RC oscillator which is configured to 8MHz.
