I haven't gone through the PAM register throughly, I need to read the specification
Any tips on how to set the PAM register.
Also I have one question, along with this, I have some more registers like AGPCMD, AGPSTAT and etc..
to set the properties of the AGP port. Do I need to take care of these while configuring the DDR SDRAM.
