    S25FL256S : How to setting Configure Register




      I'm using the S25FL256S with EFM32GG11 of Silicon Labs.

      And I have a sample code for 'MX25L25635F'.

      I have tried to set to Quad mode.

      But I couldn't set it.


      I understand that the 'S25FL256S' has Quad mode register in Configuration Register.


      I'm trying to set register as below in EFM32GG11.

      qspi->FLASHWRDATALOWER = buffer[0];  // Status Register

      qspi->FLASHWRDATAUPPER = buffer[1];  // Configuration Register


      It can't update the Configuration Register, but the Status Register can it.

      Is it need a command for updating the Configuration Register?
