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?

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,
