"In the context of computing, interrupt latency is the time between when an interrupt call in the computer software is initiated and when it begins to perform the interrupt. Increased latency or delay may cause conflicts or performance issues within the system. The way I typically address this is to create some small ISR routines. These reduce the latency and make the system function faster and without conflicts."
