Note:
1. The symbols used for timing specifications follow the pattern of t
inputs and t
receive timing (RMR) with respect to the time data input signals (D) reach the valid state (V) relative to the t
reference (K) going to the high (H) state or setup time. Also, t
the time data input signals (D) went invalid (X) relative to the t
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
convention is used with the appropriate letter: R (rise) or F (fall).
