23.6.3 MII Async Inputs Signal Timing (CRS and COL)
Table 23-13 lists MII asynchronous inputs signal timing.
Figure 23-13 shows MII asynchronous input timings listed in Table 23-13.
23.6.4 MII Serial Management Channel Timing (MDIO and
Table 23-14 lists MII serial management channel timings. The FEC functions correctly
with a maximum MDC frequency of 2.5 MHz.
