Interrupt control and state register

WebInterrupts are the events that temporarily suspend the main program, pass the control to the external sources and execute their task. It then passes the control to the main program where it had left off. 8051 has 5 interrupt signals, i.e. INT0, TFO, INT1, TF1, RI/TI. Each interrupt can be enabled or disabled by setting bits of the IE register ...

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.
