  1. The test conditions SD/SDIO standard mode (default speed mode) use an 8 mA drive strength, fast slew rate, and a 30 pF load. For SD/SDIO high-speed mode, the test conditions use a 12 mA drive strength, fast slew rate, and a 30 pF load. For other SD/SDIO modes, the test conditions use a 12 mA drive strength, fast slew rate, and a 15 pF load.
  2. This specification is achieved using pre-determined DLL tuning.
  3. This specification is required for capturing input data using DLL tuning.
