this is my question(ATMega16)
can you tell my if i have the TCCR1B set to external clock source on T1 pin clock on rising edge , what is the principle by what the ATMega16 TCNT1 counts ?
I mean i have a circuit that measure the resonant frequency of a LC circuit and the output of this circuit(a square wave) enters on T1 pin clock. The resonant frequency is f1.How does ATMega16 to count exact this value?
and if i have a 7.3728 MHz quartz oscillator as clock what do you think it will be the maximum frequency that ATMega16 will count ?
