CONFIGURATION REGISTER
READ/WRITE
The Configuration Register holds bits that define the adapter configuration and are not expected to change during run-
time. This register is part of the EEPROM saved setup.

MII SELECT - Used to select the network interface port. When set, the LAN91C110 will use its MII port and interface a
PHY device at the nibble rate. This bit must always be set for proper chip function.
NO WAIT - When set, does not request additional wait states. An exception to this are accesses to the Data Register if not
ready for a transfer. When clear, negates ARDY for two to three clocks on any cycle to the LAN91C110.
FULL STEP - Reserved
AUI SELECT - This bit is a general purpose output port. Its value drives pin AUISEL and can be used as a general
purpose non-volatile configuration pin. Defaults low.
Reserved - Must be 0.
INT SEL1-0 - Used to select interrupt pin. The bits must remain 00 for the interrupt pin to be asserted for interrupt
indication. All other bit combinations are undefined.

A15 - A13 and A9 - A5 - These bits are compared against the I/O address on the bus to determine the IOBASE for the
LAN91C110‘s registers. The 64k I/O space is fully decoded by the LAN91C110 down to a 16 location space, therefore the
unspecified address lines A4, A10, A11 and A12 must be all zeros.
