9.5.12 10M MII: Carrier Assertion/De-Assertion (Half-Duplex Transmission)
Table 9-19 lists the significant time periods for the 10M MII carrier assertion/de-assertion during half-duplex
transmission. The time periods consist of timings of signals on the following pins:
• TXEN
• TXCLK
• CRS
Figure 9-13 shows the timing diagram for the time periods.
