Ethernet Controller Port
NOTE:
For information about initializing the 10BaseT Ethernet controller port
and for correct setup and configuration of the Ethernet, refer to the
AMD
Am79C961A PCnet-ISA+ Single Chip, Plug & Play Full Duplex Ethernet
Controller for ISA
specification, order #18183.
The following are the 8-bit and 16-bit base addresses for the Ethernet:
Base addresses: 8-bit = 220h, 16-bit = 220h
The TIP board provides an Ethernet controller port that can be run in interrupt-
driven mode. The Ethernet controller port supports software downloading and
debugging over a network. For example, the CAD-UL debugger uses this
capability.
Many devices already have an Ethernet controller port for use by the device
application. However, it is usually not possible to use the device port for running
the debugger. For example, if the system is stopped at a break point, and in the
context of the debug monitor, then the driver and TCP/IP stack cannot run.
However, the TIP board Ethernet controller port can be driven in a polled manner
and can function independently from the application drivers and protocol stacks.
All of the interrupts from the Ethernet controller are gathered into a single interrupt
signal that is connected to a dedicated pin on the interface connector or through a
shared interrupt circuit. The Ethernet controller port can run in interrupt-driven
mode.
