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).
This figure provides the AC test load for eTSEC.

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).
