    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, tMRDVKH symbolizes MII receive
    timing (MR) with respect to the time data input signals (D) reach the valid state (V) relative to the tMRX clock reference (K)
    going to the high (H) state or setup time. Also, tMRDXKL symbolizes MII receive timing (GR) with respect to the time data input
    signals (D) went invalid (X) relative to the tMRX clock reference (K) going to the low (L) state or hold time. 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 tMRX represents the MII (M) receive (RX) clock. For rise and fall times, the latter convention is used
    with the appropriate letter: R (rise) or F (fall).
