Note:
1. The symbols used for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for
inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tMTKHDX symbolizes MII transmit
timing (MT) for the time tMTX clock reference (K) going high (H) until data outputs (D) are invalid (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 tMTX represents the MII(M) transmit (TX) clock. For rise and fall times, the latter convention is
used with the appropriate letter: R (rise) or F (fall).
