LPC1768 - vector table size

Lukasz Gesieniec

Hi,

how to check size of the Interrupt Vector Table in LPC1768. I want to copy this table from flash to ram.

Regards

Parents

    You didn't read everything in the user manual.

    Look for example at figure 3 LPC17xx system memory map.

    Does the vector table seem to be 1 kB large?

    You may also look at table 51 and see if you find any vectors spanning the full kilobyte. 1kB has room for a lot of interrupt vectors, but the NVIC doesn't mention such a large number of vectors.
