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,

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).
