Note:
1. The symbols used for timing specifications herein 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).
