WebDec 1, 2014 · An interrupt is a signal that tells the processor to immediately stop what it is doing and handle some high priority processing. That high priority processing is called an Interrupt Handler. An interrupt handler is like any other void function. If you write one and attach it to an interrupt, it will get called whenever that interrupt signal is ... Web[Interrupts written in C code in the Arduino system are not reentrant (capable of correctly handling multiple overlapping executions within the same handler) but one could write a reentrant assembly language handler that reenables interrupts before it begins a time-consuming process.]
