SD_CLK clock frequency:
SD_CLK clock frequency - identification mode
SD_CLK clock low time - High speed/Full speed mode
SD_CLK clock high time - High speed/Full speed mode
SD_CLK clock rise and fall times
Input setup times: SD_CMD, SD_DATx, SD_CD to
SD_CLK
Input hold times: SD_CMD, SD_DATx, SD_CD to SD_CLK
Output delay time: SD_CLK to SD_CMD, SD_DATx valid
Notes:
1. The symbols used for timing specifications herein follow the pattern of t
2. In full speed mode, clock frequency value can be 0–25 MHz for a SD/SDIO card and 0–20 MHz for a MMC card. In high speed
3. 0 Hz means to stop the clock. The given minimum frequency range is for cases were a continuous clock is required.
4. To satisfy hold timing, the delay difference between clock input and cmd/data input must not exceed 2ns.

the invalid state (X) or output hold time. Note that, in general, the clock reference symbol representation is based on five letters
representing the clock of a particular functional. For rise and fall times, the latter convention is used with the appropriate letter:
