DRA821U: MMC pins handling

Part Number: DRA821U

Hi

How do I handle unused terminals on the MMC0 part?

The checklist stated that the MMC0_CALPAD should be open when not used.

No other terminals were mentioned.

Can I leave the rest of the terminals open when they are not in use?

Do I need to connect a power supply to VDDS_MMC0, VDDA_0P8_DLL_MMC0 even when not in use?

Thanks and Best regards,

Tsurumoto.

    Tsurumoto,

    Unused MMC0 CALPAD, CLK, CMD, DS, and DAT[7:0] should be left unconnected.  Unused MMC0 power balls should be supplied with voltage specified in Recommended Operating Conditions table; make sure to connect to sources that meet the power supply sequence requirement.

    Thanks & Regards,
