10.5.6 MII / 100M Stream Interface: Synchronous Receive Timing
Table 10-13 lists the significant time periods for the MII / 100M Stream Interface synchronous receive
timing (which consists of timings of signals on the RXD[3:0], RXDV, RXER, and RXCLK pins). Figure 10-6
shows the timing diagram for the time periods.
