Hi Rahul,

It is explained in Technical Reference Manual. It is used in Live Firmware Update. Here is copy/paste from TRM

Rahul,

The ACTIVE addresses are always 0xD00-0xEFF, and the INACTIVE addresses are always 0x0100 0900- 0x0100 0AFF.

The swap option allows you to have 2 tables with interrupt vectors, and after a Live Firmware Update, Activate the INACTIVE table.

Thanks,

Sira
