    ModeBit Reset(FFh) S25FL-S

    user_483423427

      Hello,

      Suppose that we execute ModeBit Reset(FFh) as the first instruction after power on.

      Is there any trouble to all the target devices below? Or this instruction will be ignored?

       

      S25FL128S

      S25FL256S

      S25FL512S

      S70FL01GS

      Note: In the above device, DDR is not used, only Standard SPI / Quad SPI is used.

       

      I've referenced the S25FL-S datasheet, there are a description below.

       

      >It is recommended to use the MBR command after a system reset when the

      >RESET# signal is not available or, before sending a software reset, to ensure the device is released from continuous high performance read mode

       

      I understand that there should be no issue if we execute FFh after POR, is it correct?

      Please tell if there are any attention about execute MBR command.

       

      Best Regards,

      すべての対象デバイスでは、デバイスに不都合な事が発生しますでしょうか?

      それとも、このインストラクションが無視されるだけでしょうか?
