9.5.20 10Base-T: Jabber Timing
Table 9-27 lists the significant time periods for the 10Base-T jabber. The time periods consist of timings of
signals on the following pins:
• TXEN
• TP_TX (that is, TP_TXP and TP_TXN)
• COL
Figure 9-21 shows the timing diagram for the time periods.
Note: For more information on 10Base-T jabber operations, see Section 6.5.9, “10Base-T Operation:
