9.5.7 MII Management Interface Timing

Table 9-14 lists the significant time periods for the MII Management Interface timing (which consists of

timings of signals on the MDC and MDIO pins). Figure 9-8 shows the timing diagram for the time periods.

† The ICS1893CF is tested at 25 MHz (a 40-ns period) with a 50-pF load. Designs must account for all board loading

of MDC.
