Note:
1. The symbols used for timing specifications herein follow the pattern of t
(reference)(state)
symbolizes MII transmit timing (MT) for the time t
(X). Note that, in general, the clock reference symbol representation is based on two to three letters representing the clock
of a particular functional. For example, the subscript of t
times, the latter convention is used with the appropriate letter: R (rise) or F (fall).
