EECS/FCS Pulled Low
If EECS/FCS is pulled low, this indicates that the configurations, Ethernet ID, and CIS are stored in
an EEPROM. In this case, after a power-on reset the PENTIC+ will load the configurations into the
LAN configuration registers and the Ethernet IDs and CIS into the higher half of SRAM memory (with
auto-mapping to ID registers and attribute memory space, respectively). Since the EEPROM used is
a 93C66, a serial EEPROM storage device, the access time is quite long and the system has to wait
for the loading sequence (refer to PCMCIA R2.1). Loading a word of EEPROM typically takes 34
μ
S.
The exact time for EEPROM loading depends on the length of CIS but must not exceed 10 mS.
