This register can be used as a way of storing

and retrieving non-volatile information in the

EEPROM to be used by the software driver. The

storage is word oriented, and the EEPROM

word address to be read or written is specified

using the six lowest bits of the Pointer Register.

This register can also be used to sequentially

program the Individual Address area of the

EEPROM, that is normally protected from

accidental Store operations.

This register will be used for EEPROM read and

write only when the EEPROM SELECT bit in the

Control Register is set. This allows generic

EEPROM read and write routines that do not

affect the basic setup of the LAN91C100.
