WebMar 5, 2010 · Latency for such an interrupt, then, is consistently on the order of 50 cycles. Note that even the simplest interrupts take on the order of 50 cycles by the time the microcontroller saves the context for a limited number of registers, accesses a peripheral, saves the data, restores the context and suffers a pipeline flush. 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.
