1. The symbols used for timing specifications herein follow the pattern of t
2. Signal timings are measured at 0.7 V and 1.9 V voltage levels.

general, the clock reference symbol representation is based on three letters representing the clock of a particular functional.
For example, the subscript of t
used with the appropriate letter: R (rise) or F (fall).
