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.
