Note:
1. The symbols used for timing specifications herein follow the pattern of t(first three 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, tRMRDVKH
symbolizes RMII receive timing (RMR) with respect to the time data input signals (D) reach the valid state (V) relative to the
tRMX clock reference (K) going to the high (H) state or setup time. Also, tRMRDXKL symbolizes RMII receive timing (RMR) with
respect to the time data input signals (D) went invalid (X) relative to the tRMX 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 tRMX represents the RMII (RM) reference (X) clock. For rise and fall
times, the latter convention is used with the appropriate letter: R (rise) or F (fall).
