In this tutorial, we will talk about the interrupt vector table. Firstly, we will define the interrupt vector table (IVT). Secondly, we will see the role of IVT for interrupts and exceptions processing in microcontrollers or microprocessors. After that, we will see the interrupt vector table o...
(a) The interrupt vector table for the Intel microprocessor; (b) the contents of an interrupt vector. In an interrupt vector table, the first five interrupt vectors are identical in all Intel microprocessor family members, from the 8086 to the Pentium. Other interrupt vectors exist for the ...
The interrupt vector may be coded in C as an array of pointers to functions, thus: void (*interrupt_vector[])()= { alpha, beta, gamma }; This interrupt vector has three entries, which point to three interrupt service routines, implemented as C functions: alpha(), beta(), and gamma(...
ARM processors typically have the vector table starting at address 0x00000000 or 0xFFFF0000, depending on the mode or configuration. In some microcontrollers, like AVR, the IVT is placed at the beginning of the program memory (address 0x0000). 5. Memory Constraints in Embedded Systems In embedd...
A management unit (1) for microcontrollers equipped with a decoder (4) for a plurality (2N) of interrupt channels (2) is of a type connected to a central processing unit (11) of the microcontroller to decode and transfer thereto a single interrupt digital signal through said decoder (4),...
i have set every thing and its evident from all the flags that interuptis being generated by ePWM modula and then propogated all the way to IFR in Core but intrrupt is not trigered i mean control doesnt jump to my ISR i think there is some problem with my inter...

The MAXQ family of microcontrollers has a register IV (Interrupt Vector) which holds the address of the interrupt routine, and a bit INS (Interrupt iN Service) to indicate an interrupt activity. When an interrupt is triggered, the processor core behaves as if "call IV" and "move INS,#1" ...
Memory Segments in ARM Cortex-M Microcontrollers Memory Mapped Peripherals in ARM Relocating ISR Address from IVT Coming back to the main discussion, the code memory region contains an interrupt vector table (IVT). This interrupt vectors table consists of a reset address of stack pointer and starti...
