I would like to extract the Background attribute without using DMA. What should I do?
I have a pointer for the attribute file.. say "BG01_BAddr"
as the pointer is defined as .LWORD, it occupied 4 bytes. I know that it is a 24-bits address, therefore, BG01_BAddr, BG01_BAddr+1 and BG01_BAddr+2 should represent the LOW, MED and HIGH byte of the 24-bit address.
However, how can I get the contact of the attribute using this 24-bit address?

Thanks very much.
