21489 SDRAM access using PM

Hi

 

I have 16 MBytes of SDRAM memory mapped to /MS3, 0x0C00_0000 in 32-bit space and I want to access that as a 48-bit memory.  HRM rev 0.3 pg 3-14 does not help me in calculating the address.  Pg 7-18 of the Programming reference manual doesn't help either with external accesses.

 

Can you please provide a more complete address mapping table? Specifically:

 

Bank 0 :

32-bit Address = 0x00200000

48-bit Address = ??

 

Bank 1:

32-bit Address = 0x04000000

48-bit Address = ??

 

Bank 2:

32-bit Address = 0x08000000

48-bit Address = ??

 

Bank 3:

32-bit Address = 0x0C000000

48-bit Address = ??

 

PKDIS = 0, and I'm running using 16-bit bus.
