the referenced data signals (D) reach the invalid state (X) or hold time. In general, the clock reference symbol is based on
three letters representing the clock of a particular function. For example, the subscript of t
(TX) clock. For rise and fall times, the latter convention is used with the appropriate letter: R (rise) or F (fall).
