In summary, the interrupt vector table is an array of function pointers that points to the starting address of exception or interrupt handlers of a microcontroller or microprocessor. IVT usually stores at the starting addresses of flash or code memory. Further Reading: Nested Vectored Interrupt Contr...
interruptNumberspecifies the interrupt in question. This function gets the priority of an interrupt. SeeInterrupt_setPriority()for a definition of the priority value. SeeInterrupt_enableInterruptfor details about the interrupt parameter Returns Returns the interrupt priority, or -1 if an invalid interrup...
Microprocessor interrupts are divided into fault, trap or abort conditions. For fault conditions, the instruction that caused the fault is retried after the interrupt service routine has been executed. For trap conditions, the next instruction in the program being run by the CPU is executed after ...
In the above tale from the trenches, the trailing-edge interrupt was not needed. So why was it implemented that way in the first place? It was because that was the definition of the protocol. In that particular application, the trailing edge interrupt was not needed but in other applications...

Definition:It is referred to as an inputsignalthat has the highest priority for hardware or software events that requires immediate processing of an event. During the early days of computing, theprocessorhad to wait for the signal to process any events. The processor should check every hardware ...
Microprocessor boot code (4) Initiate interrupt vectors The initialization of the system during POST creates interrupt vectors to the proper interrupt handling routines and sets up registers with parameters. In Figure 15.2, the interrupt vector table is included in the boot sector program, thus initia...
A problem facing processor developers, particularly in the case of embedded processors for system on chip (SOC) implementations, is the definition of the processor instruction set in view of the widely expanding variety of applications that processors and SOC chips are being designed into. Without ...
