RA[16:2]
Outputs. This bus specifies the buffer RAM
doubleword being accessed by the LAN91C110.
nROE
O4
Output. Active low signal used to read a
doubleword from buffer RAM.
Outputs. Active low signals used to write any
byte, word or dword in RAM.
An external 25 MHz crystal is connected across
these pins. If a TTL clock is supplied instead, it
should be connected to XTAL1 and XTAL2 should
be left open.
I with pullup Input. General purpose input port used to convey
LINK status (EPHSR bit 14).
O4
Output. Non volatile output pin. Driven by AUI
SELECT (CONFIG bit 8).
O12
Output to MII PHY. Envelope to 100 Mbps
transmission.

Input. Indicates a code error detected by PHY.
Used by the LAN91C110 to discard the packet
being received. The error indication reported for
this event is the same as a bad CRC (Receive
Status Word bit 13).
