Dear All,

I am a little confused in interfacing SDRAM to MPC8270 processor's chipselect.
That is, what is the maximum size of SDRAM that i can interface with processor's chipselect.
From MPC8280 reference manual (page no 425) it is stated that maximum size is 128Mbytes .
On the other side, of you refer to manual's (page number 436) it is stated that maximum size is 4GB. (128 MB if page based interleaving is disabled).
Kindly help me with this confusion.

Regards
