to high (H). Also t
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).
Measured at capacitive load of 40 pF.
For reference only, according to the SD card specifications.
Average, for reference only.
