DESCRIPTION
Input. This input is used to complete synchronous
read cycles. In EISA burst mode it is sampled on
falling LCLK edges, and synchronous cycles are
delayed until it is sampled high.
Outputs. Only one of these interrupts is selected to
be used; the other three are tri-stated. The
selection is determined by the value of INT SEL 1-
0 bits in the Configuration Register.
Output. This active low output is asserted when
AEN is low and A4-A15 decode to the
LAN91C100FD address programmed into the high
byte of the Base Address Register. nLDEV is a
combinatorial decode of unlatched address and
AEN signals.
Input. Used in asynchronous bus interfaces.

Input. When nDATACS is low, the Data Path can
be accessed regardless of the values of AEN, A1-
A15 and the content of the BANK SELECT
Register. nDATACS provides an interface for
bursting to and from the LAN91C100FD 32 bits at
a time.
Output. 4
μ
sec clock used to shift data in and out
of the serial EEPROM.
Output. Serial EEPROM chip select. Used for
selection and command framing of the serial
EEPROM.
Output. Connected to the DI input of the serial
EEPROM.
Input. Connected to the DO output of the serial
EEPROM.
Input. External switches can be connected to these
lines to select between predefined EEPROM
configurations.
Input.
Enables

LAN91C100FD accesses to the serial EEPROM.
Must be grounded if no EEPROM is connected to
the LAN91C100FD.
Bidirectional. Carries the local buffer memory read
and write data. Reads are always 32 bits wide.
Writes are controlled individually at the byte level.
Floated if FLTST=1 during RECEIVE FRAME
STATUS WORD writes for packet forwarding
information (RA2-RA16=0, RCVDMA=1, nRWE0-
