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.
