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.
Output. This pin is active during LAN91C100FD
write memory cycles of receive packets.
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.
