EEPROM Fields
Table 3-4 summarizes the layout of the data stored in an EEPROM connected to the IP1000A LF. Most
defined EEPROM fields are read from the EEPROM and loaded into unique register bit positions within
the IP1000A LF during auto initialization.
In Table 3-4, all locations marked “Unused” and all locations not shown are not utilized by the IP1000A
LF.
