46.18.4.1 Timing conditions
46.18.4.2 Timing constraints
Note:
1. For EMAC output signals, minimum and maximum access time are defined. The minimum access time is
the time between the EDMC rising edge and the signal change. The maximum access timing is the time
between the EDMC rising edge and the signal stabilizes..
