26.3.4 Ethernet MAC Frame Formats
26.3.4.1 Overview
The IEEE 802.3 Standard defines the Ethernet frame format as follows: An Ethernet frame
has a minimum length of 64 bytes and a maximum length of 1518 bytes or more if jumbo
frames are supported, excluding the preamble and the start frame delimiter bytes. An Ethernet
frame consists of the following fields:
Freescale Semiconductor, Inc.
• Seven bytes preamble
• Start frame delimiter (SFD)
• Two address fields
• Length or type field
• Data field
• Frame check sequence (CRC value)
• An EXTENSION field is defined only for gigabit Ethernet half-duplex implementations
and is not supported by the MAC core
