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 LAN91C94.
