5.7.5 EXAMPLES OF EEPROM FORMAT INTERPRETATION
5.7.5.1 LAN9500/LAN9500i
Table 5-62 and Table 5-63 provide an example of how the contents of a EEPROM are formatted in the case of
LAN9500/LAN9500i. Table 5-62 is a dump of the EEPROM memory (256-byte EEPROM), while Table 5-63 illustrates,
byte by byte, how the EEPROM is formatted.
