WebAn interrupt service routine (ISR) is a software routine that hardware invokes in response to an interrupt. ISR examines an interrupt and determines how to handle it executes the … WebAn interrupt service routine (ISR) is a software routine that hardware invokes in response to an interrupt. ISR examines an interrupt and determines how to handle it executes the handling, and then returns a logical interrupt value. If no further handling is required the ISR notifies the kernel with a return value. WebAn interrupt is a signal to the processor emitted by hardware or software indicating an event that needs immediate attention. Whenever an interrupt occurs, the controller completes the execution of the current instruction and starts the execution of an Interrupt Service Routine (ISR) or Interrupt Handler.

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\$ –
