What happens when an ISR is running and another interrupt …

WebWhen the interrupt handler (ISR) for the first interrupt is complete, the NVIC sees a second interrupt pending, and runs that ISR. This is quite wasteful since the middle POP and PUSH are moving the exact same processor state back and forth to stack memory. If the interrupt handler could have seen that a second interrupt was WebOct 1, 2024 · When an interrupt takes place, the processor will determine the start address of the ISR from a vector table automatically. By default the vector table is placed in the beginning of the memory space, but can be relocated to another address location by a bootloader or by user software. ...

WebHardware interrupt—An exception caused by an explicit hardware request signal from an external device. A hardware interrupt diverts the processor’s execution flow to a ISR, to ensure that a hardware condition is handled in a timely manner. Implementation-dependent instruction—A Ni os II processor instruction that is not Weban interrupt. The address of an ISR is defined in an interrupt vector . The MSP430 uses vectored interrupts where each ISR has its own vector stored in a vector table located at the end of program memory. Note: The vector table is at a fixed location (defined by the processor data sheet), but the ISRs can be located anywhere in memory. Interrupts

Websignaled via NMI pin; Synchronous interrupts, usually named exceptions, handle conditions detected by the processor itself in the course of executing an instruction.
