PCMCIA Attribute Memory
Address 0- 7FFEh
The Attribute Memory is implemented using an external parallel EEPROM, ROM or Flash ROM. A parallel
EEPROM (or equivalent external device) must be used for CIS.
In LOCAL BUS mode, serial EEPROM is used for configuration and IEEE Node address making it software
compatible to the LAN9xxx family of Ethernet LAN Controllers. The EEPROM is optional for both LOCAL BUS
and PCMCIA requiring a Minimum size of 64 X 16 bit word addresses.
The LAN91C96 generates the appropriate control lines (nFCS and nFWE) to read and write the Attribute
memory, and it tri-states the data bus during external Attribute Memory accesses. Only even locations are
used.
