I would like to know if an external interrupt on INT0 can make TCNT1 count.(internal clock source)
As far as the datasheet INT0 works with TCNT0 and INT1 works with TCNT1, but using an external interrupt can INT0 be used to make TCNT1 count?(internal clock source)
Then is it possible to read any 16 bit register direct or should the HIGH and LOW be read separate and then combined into one 16 bit register?
I found many web sites explaining counters but no clear explanation on the above.
