About This Manual
This document provides a functional description of the Ethernet Media Access Controller (EMAC) and
physical layer (PHY) device Management Data Input/Output (MDIO) module integrated in the device.
Included are the features of the EMAC and MDIO modules, a discussion of their architecture and
operation, how these modules connect to the outside world, and the registers description for each module.
Notational Conventions
This document uses the following conventions.
• Hexadecimal numbers are shown with the suffix h. For example, the following number is 40
hexadecimal (decimal 64): 40h.
• Registers in this document are shown in figures and described in tables.
– Each register figure shows a rectangle divided into fields that represent the fields of the register.
Each field is labeled with its bit name, its beginning and ending bit numbers above, and its
read/write properties below. A legend explains the notation used for the properties.
– Reserved bits in a register figure designate a bit that is used for future device expansion.
