FMC SDRAM mapping section - mistake between reference manuals?
Hi,
Is there mistake between reference manual RM0486 and RM0090 in section SDRAM adress mapping?
Where in RM0486 is: "When interfacing with a 16-bit memory, the FMC internally uses the ADDR[11:1] internal address lines to generate the external address. When interfacing with a 32-bit memory, the FMC internally uses
ADDR[12:2] lines to generate the external address. Whatever the memory width, FMC_A[0] has to be
connected to the SDRAM A[0].The AutoPrecharge is not supported. However, FMC_A[10] must be connected to SDRAM A[0]"
In RM0090 is: "When interfacing with a 16-bit memory, the FMC internally uses the HADDR[11:1] internal AHB address
lines to generate the external address. When interfacing with a 32-bit memory, the FMC internally uses
HADDR[12:2] lines to generate the external address. Whatever the memory width, FMC_A[0] has to be
connected to the external memory address A[0]. The AutoPrecharge is not supported. FMC_A[10] must be connected to the external memory address A[10] but it is always driven ‘low’."
For me, its logically looks like the mistake is in RM0486, and the FMC_A [10] must to be connected to memmory A[10] input.
But, is it right?
Thanks a lot,
R.
