9.5.4 100M MII: Synchronous Transmit Timing
Table 9-11 lists the significant time periods for the 100M MII Interface synchronous transmit timing. The
time periods consist of timings of signals on the following pins:
• TXCLK
• TXD[3:0]
• TXEN
• TXER
Figure 9-5 shows the timing diagram for the time periods.
