Ethernet Management Interface Electrical Characteristics
The electrical characteristics specified here apply to MII management interface signals MDIO
(management data input/output) and MDC (management data clock). The electrical characteristics for
MII, and RMII are specified in Section 8.1, “Ethernet Controller (10/100 Mbps)—MII/RMII Electrical

Note:
1. The symbols used for timing specifications 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).
