Address BUS: These pins supply addresses to the
system.
These pins should be connected to the address BUS of
the LAN controller.
Address BUS MSB.
This pin should be connected to the LAN controller’s
address BUS MSB.
In the future, this pin may be changed to a General
Purpose Output (GPIO Z7).
Data BUS: These pins supply data to/from the system.
These pins should be connected to the data BUS of the
LAN controller.
BUS HIGH Enable: This pin and the least-significant
address bit (A0) indicate to the system which bytes of
the data BUS (upper, lower, or both) participate in a
BUS cycle. The -BHE and A0 pins are encoded as
shown in the table below.
This pin should be connected to -BHE on the LAN
controller.
