External clock source characteristics
WebExternal Clock Sources There are several possible external clock sources, all sharing the XTAL1 and XTAL2 pins. Of course, this means that only one source can be enabled … WebA timer module can also operate in a counter mode where the clock source is not known, it’s actually an external signal. Maybe from a push button, so the counter gets incremented every rising or falling edge from the button press. ...
