Notes:
1. The symbols used for timing specifications herein follow the pattern of t(first three letters of functional block)(signal)(state)
(reference)(state) for inputs and t(first three letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tSFSIXKH
symbolizes eSDHC full mode speed device timing (SFS) input (I) to go invalid (X) with respect to the clock reference (K)
going to high (H). Also tSFSKHOV symbolizes eSDHC full speed timing (SFS) for the clock reference (K) to go high (H), with
respect to the output (O) going valid (V) or data output valid 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: R (rise) or F (fall).
2. Measured at capacitive load of 40 pF.
3. For reference only, according to the SD card specifications.
4. Average, for reference only.
