The interrupt handler executes several interrupt service routines (ISRs).Each ISR is a function related to a single device sharing the IRQ line. Because it is not possible to know in advance which particular device issued the IRQ, each ISR is executed to verify whether its device needs attention; if so, the ISR performs all the operations that need to …

WebDescription. Use the Hardware Interrupt block to create an interrupt service routine (ISR) automatically in the generated code of your model. The ISR executes the downstream function-call subsystem associated with event ports of the block. The function call subsystem associated with the event output port run at same priority as that of ISR priority. WebFeb 20, 2015 · The interrupt is being set to fire on a change, and your test_func is set as the Interrupt Service Routine (ISR), called to service that interrupt. The ISR then prints the value of the input. At first glance you would expect the output to be as you have said, and alternating set of high lows, as it only gets to the ISR on a change.
