WebAn interrupt is the automatic transfer of software execution in response to a hardware event that is asynchronous with the current software execution.This hardware event is called a trigger.The hardware event can either be a busy to ready transition in an external I/O device (like the UART input/output) or an internal event (like bus fault, memory fault, or a … WebThe register TMSK1 is a control register that is used to "arm the input capture interrupt. Arming the input capture interrupt IC1, for instance, is accomplished by setting bit IC1I in register TMSK1.
