timing (GR) with respect to the time data input signals (D) went invalid (X) relative to the t
going to the low (L) state or hold time. Note that, in general, the clock reference symbol representation is based on
three letters representing the clock of a particular functional. For example, the subscript of t
(M) receive (RX) clock. For rise and fall times, the latter convention is used with the appropriate letter: R (rise) or F
(fall).
