Test Interface Port (TIP) (A16)
The PCI CDP includes a connector for the AMD Test Interface Port (TIP) board.
The TIP board is used for testing and debugging AMD embedded product customer
development platforms. It connects through a ribbon cable to the TIP connector
on the platform.
The TIP board provides a collection of peripherals, such as LEDs, hexadecimal
displays, an LCD display, two serial ports, a parallel port, an Ethernet controller,
and Flash memory, that can be convenient in system development.
The PCI CDP’s TIP connector resides on the ISA bus and can use the ISA interrupt
request (IRQ) signals if a TIP board is connected. Individual TIP connector IRQ
signals are listed in Table 2-5. See the TIP board documentation for I/O addressing
information.
NOTE: The TIP board’s IRQ usage can conflict with the PCI CDP’s onboard PC
peripherals. Some TIP or CDP peripherals may not operate correctly when the TIP
board is in use.
