10.5.8 10M Media Independent Interface: Receive Latency
Table 10-15 lists the significant time periods for the 10M MII timing. The time periods consist of timings of
signals on the following pins:
• TP_RX (that is, the MII TP_RXP and TP_RXN pins)
• RXCLK
• RXD
Figure 10-9 shows the timing diagram for the time periods.
