WebMay 29, 2024 · The mask bits, ISR flags etc, are just resources that enable you to control what can interrupt what and when. Whether interrupts have to generate the response in 10 clock cycles or 1000 affects whether you must use a vectored interrupt, or can wait for a non-vectored one to find out why it's been invoked, and it is again very application specific. WebStep 10: Configure ADC Hardware. This is done through setting bits in the control registers for the ADC. First, let's set the prescalar for the ADC. According to the datasheet, this prescalar needs to be set so that the ADC input frequency is between 50 KHz and 200 KHz. The ADC clock is derived from the system clock.
