9.5.11 100M MII: Carrier Assertion/De-Assertion (Half-Duplex Transmission)
Table 9-18 lists the significant time periods for the 100M 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 9-12 shows the timing diagram for the time periods.
