Notes:
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, tGRDVKH symbolizes GMII receive
timing (GR) with respect to the time data input signals (D) reaching the valid state (V) relative to the tRX clock reference (K)
going to the high state (H) or setup time. Also, tGRDXKL symbolizes GMII receive timing (GR) with respect to the time data
input signals (D) went invalid (X) relative to the tGRX 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 tGRX represents the GMII (G) receive (RX) clock. For rise and fall times, the latter convention
is used with the appropriate letter: R (rise) or F (fall).
