Nios II Exception Vector

Hi everyone,

i have a question about the Nios II exception vector.

Why is the default offset of the general exception vector 0x20 ?

The Nios II handbook writes:

Offset allows you to specify the location of the exception vector relative

to the memory module’s base address

Can i also select 0x00 in place of 0x20 for the offset ?

regards,

Nicolas
