  1. The test condition settings for the eMMC modes are: 12 mA drive strength, fast slew rate, and a 15 pF load. The OTAP delay (OTAP_DLY[5:0] ) test condition settings are: eMMC high-speed SDR mode = 0x05, eMMC high-speed DDR mode = 0x05, and eMMC HS200 mode = 0x02.
  2. EMIO is supported in the eMMC standard mode.
  3. This specification is achieved using predetermined DLL tuning.
  4. This specification is required for capturing input data using DLL tuning.
