Notes
1. Rise and fall times are measured from 10% to 90% of voltage level.
2. CLK referenced to VIH min and VIL max.
3. CMD and DAT inputs and outputs referenced to CLK.
4. 0Hz means to stop the clock. The given minimum frequency range is for cases where a continuous clock is
required
5. Specified for one card
