DESCRIPTION
Local Bus - Outputs. Active high interrupt signals. The
interrupt line selection is determined by the value of INT
SEL1-0 bits in the Configuration Register. These interrupts
are tri-stated when not selected.
Local Bus - Active low output asserted in 16 bit mode when
AEN is low and A4-A15 decode to the LAN91C96I address
programmed into the high byte of the Base Address
Register.
Local Bus, - Input. Active low read strobe used to access the
LAN91C96I IO space.
Local Bus - Input. Active low write strobe used to access the
LAN91C96I IO space.
Local Bus - Active low signal used by the host processor to
read from the external ROM.
Output. 4usec clock used to shift data in and out of a serial
EEPROM.
Output. Serial EEPROM chip select.
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. The
values of these pins are readable.
Input. External switches can be connected to these lines to
select between predefined EEPROM configurations. The
values of these pins are readable.
INTERNAL ENDEC - Transmit LED output.
EXTERNAL ENDEC - Active low Transmit Enable output.
INTERNAL ENDEC - Board Select LED activated by
accesses to I/O space (nIORD or nIOWR active with AEN
low and valid address decode for Local Bus). The pulse is
stretched beyond the access duration to make the LED
visible.
EXTERNAL ENDEC - NRZ receive data input.
INTERNAL ENDEC - Receive LED output.
EXTERNAL ENDEC - Receive clock input.
INTERNAL ENDEC - Link LED output.
EXTERNAL ENDEC - Transmit Data output.
