9.5.10 10M Serial Interface: Transmit Latency
Table 9-17 lists the significant time periods for the 10M Serial Interface transmit latency. The time periods
consist of timings of signals on the following pins:
• 10TXEN (the 10M Serial Interface mapping of the 10M/100M MII TXEN pins)
• 10TCLK (the 10M Serial Interface mapping of the 10M/100M MII TXCLK pins)
• 10TD (the 10M Serial Interface mapping of the 10M/100M MII TXD0 pins)
• TP_TX (the MDI mapping of the 10M/100M MII TP_TXP and TP_TXN pins)
Figure 9-11 shows the timing diagram for the time periods.
