[ts-7000] SDRAM SIGNALS

[joel garner <>]

Dear all,

 

on the ts7250 all the SDRAM control signals are directly interfaced to the chips, but EP_RD and EP_WR  are conected to the cpld, can anyone throw some light on that.

 

Curtis wrote once:

 

"The CPLD also converts the SRAM bus control signals to RD, WR, and CS signals for flash."

 

is that the reason why signals are connected to the cpld??

if it is,then why is it that we need sdram signals to to control flash, since we already have flash controller dedicated for this purpose on the 9302 chip.

 

chill,

joel
