Hi ,



Please let me know with regards the following with regards to TS201 ,


1 . When using SDRAM in shared operation SDCKE is shared and connect to CKE , and should it have a external pullup.

     Data sheet states that Master DSP has internal pull up and pull down .


2. What is condition of SDCKE after power on RESET .

    Is it that Master DSP uses internal Pull down and output Low (SDRAM inself refresh mode ),  

    Is it that master uses Internal pull down and output Low(SDRAM in Suspend mode ),
