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 LAN91C100FD.
