hi!
i am interfacing an SDRAM with ADSP-21065L EZ kit Lite board for
memory expansion using EMAFE. the problem is, there are pins in SDRAM
that are not specified in the dsp board. the following are the pins
that i don't know where to connect :) :
write enable
chip select
clock enable
row address strobe
column address strobe
data input/output mask
the SDRAM i'm using operates at 133MHz. will i connect the clock of
the SDRAM to the transmit clock of the EMAFE?
thank you!

Some info are in Handbook of EZ kit 21065L
7 pin con. named J9 on the board has those singnals
Handbook says that EMAFE is exp. slot for user designed boards with codecs.
This handbook also have a schematic of system board i think it would be heplfull . System clock is 33Mhz internal DSP clock is 66Mhz.
