AN90799 - PSoC® 4 Interrupts
Interrupts are an important part of any embedded application. They free the CPU from having to continuously poll for the occurrence of a specific event; it notifies the CPU only when that event occurs. In system-on-chip (SoC) architectures such as PSoC, interrupts are frequently used to communicate the status of on-chip peripherals to the CPU.
