Description The ATMega16 chip in the M16 has a real-time counter that operates asynchronously when a 32,768hz watch crystal is connected to it, providing a real-time clock. Bascom has built-in support for the RTC, making it very easy to use time functions. The watch crystal needs to connect to pins TOSC1(pin 28) and TOSC2(pin 29).
