    FX3S eMMC power management

    DaBo_288066

      Hi all,

         

      is there a specific API function to put the attached eMMC device in low-power mode and restore (sleep/awake CMD5 command)?

         

      Can you provvide an example?

         

       

         

      Thanks a lot!

          Hi,

             

          You can use the CyU3PCardMgrSendCmd command to send command to the eMMC. The command parameter in the API should be  CY_U3P_SD_MMC_CMD12_STOP_TRANSMISSION (cmd5).

             

          Please refer the Api guide for more details on how to use this API.

             

          Regards,

            Hi, thanks for your response.

               

            Sorry but I cannot find into the Api guide the meaning of "flags" parameter of CyU3PCardMgrSendCmd.

               

            Also, what's the difference between CyU3PCardMgrSendCmd and CyU3PSibVendorAccess functions? (exept the embedded response support)

               

            Regards,
