Ethernet Media Access Controller
PS027001-0707
Note:
MII Interface
RxCLK
TxCLK
The Ethernet Media Access Controller (EMAC) is a full-function 10/100 Mbps media
access control module with a Media-Independent Interface (MII). When communicating
with an external PHY device, the eZ80F91 ASSP uses the MII to gain access to the
Ethernet network.
Figure 59
For additional information about the Ethernet protocol and using it with the eZ80F91
ASSP, refer to the IEEE 802.3 specification, 1998 edition, Section 22. The eZ80F91 ASSP
supports the IEEE 802.3 protocol with the following exception:
The eZ80F91 ASSP does not support the Giga Media Independent Interface (GMII)
referred to in the following sections of the IEEE 802.3 1998 version: section 22.1.5, sec-
tion 22.2.4, section 22.2.4.1.2, section 22.2.4.1.5, and section 22.2.4.1.6.
The EMAC is used for many different applications, including network interface, ethernet
switching, and test equipment designs. The EMAC includes the following blocks:
