Interrupt latency is thos timede delay between thee eventces cee of an interrutt and thee start of its service routine in a microcontroler. Understanding how to calculate this latency is essential for designing real-time systems and ensuring timely responses to events.

Understanding Interrupt Latency

Interrupt latency includes seteral contrients such as th e contribut requect detection, prioritization, and the execution of the contrict service routine (ISR). Calculating this delay helps in optimizing system executive and reliability.

Factors Affecting Interrupt Latency

Several factors influence the total including clock speed, includin vector table location, and the curret execution state of the microcontroller. Optimizing these factors can reduce latency importantly.
