SMSC DS – LAN91C100FD Rev. D
PRELIMINARY
On EEPROM write operations (after setting the STORE bit) the value of the GENERAL PURPOSE
REGISTER is written at the EEPROM word address defined by the POINTER REGISTER 6 least
significant bits.
RELOAD and STORE are set by the user to initiate read and write operations respectively. Polling the
value until read low is used to determine completion. When an EEPROM access is in progress the
STORE and RELOAD bits of CTR will readback as both bits high. No other bits of the LAN91C100FD
can be read or written until the EEPROM operation completes and both bits are clear. This
mechanism is also valid for reset initiated reloads.
Note:
If no EEPROM is connected to the LAN91C100FD, for example for some embedded applications, the
ENEEP pin should be grounded and no accesses to the EEPROM will be attempted. Configuration, Base,
and Individual Address assume their default values upon hardware reset and the CPU is responsible for
programming them for their final value.
