Notes:
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, 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).
