9.3.3
Figures 9.4 (a) to (f) show the timing for various kinds of MII frames. The normal timing for
frame transmission is shown in figure 9.4 (a), the timing in the case of a collision during
transmission in figure 9.4 (b), and the timing in the case of an error during transmission in figure
9.4 (c). The normal timing for frame reception is shown in figure 9.4 (d), and the timing in the
case of errors during transmission in figures 9.4 (e) and (f).
