Data FIFO Direct Access Select: When driven
high, all accesses to the LAN9311/LAN9311i are
directed to the RX and TX Data FIFO’s. All reads
are from the RX Data FIFO, and all writes are to
the TX Data FIFO. In this mode, the address input
is ignored. Refer to
Access Mode," on page 168
information.
Endianess Select: When this signal is set high,
big endian mode is selected. When low, little
endian mode is selected. This signal may be
dynamically changed or held static. Refer to
Chapter 8, "Host Bus Interface (HBI)," on page 99
for additional information.
EEPROM Microwire Data Input (EEDI): In
Microwire EEPROM mode (EEPROM_TYPE = 0),
this pin is the Microwire EEPROM serial data input.
EEPROM I
(EE_SDA): In I
(EEPROM_TYPE = 1), this pin is the I
serial data input/output.
Note:
EEPROM Microwire Data Output: In Microwire
EEPROM mode (EEPROM_TYPE = 0), this pin is
the Microwire EEPROM serial data output.

Note:
EEPROM Type Strap: Configures the EEPROM
type. See
