WebJan 29, 2024 · An interrupt vector table is a data structure that associates a list of interrupt handlers with a list of interrupt requests in a table of interrupt vectors . Each entry of the interrupt vector table, called an interrupt vector, is the address of an interrupt handler. While the concept is common across processor architectures, IVTs may be ... WebIn the code below, with the first line in the void setup, we enable PCIE2 because D5 corresponds to that group. With the second line we indicate taht PCINT21 will trigger interrupt because D5 is represented by taht group. Everything is set bwe we need to define the ISR vector. To pin D5 which is from port D, the ISR that corresponds is vector 2.
