WebDec 7, 2016 · ISR: Stands for "Interrupt Service Routine." An ISR (also called an interrupt handler) is a software process invoked by an interrupt request from a hardware device. It handles the request and sends it to the CPU , interrupting the active process . When the ISR is complete, the process is resumed. Web\$\begingroup\$ The other thing I see, is that the timer interrupt is being called every 64 clock cycles (CS20 and CS21 = 64 prescaling and OCR1A = 1), and maybe is being triggered when the micro is "busy" doing the ADC interrupt function. At least, the Timer vector function takes more than 64 clock cycles itself. \$\endgroup\$ – maryland express care
