Test Interface Port (TIP)
The test interface port (also available from AMD, but not included with the ISDN
TA reference design) provides an interface to a low-cost AMD development board.
This board is useful for testing, debugging, and developing software on AMD’s
reference designs. It contains an 8-bit Flash memory device, LEDs, hexadecimal
displays, an LCD, serial ports, a parallel port, and an Ethernet controller.
In the event of a Flash memory failure on the main board, you can boot the ISDN
TA from an external TIP board. Refer to the Am186

that the TIP board and user’s manual are available from AMD, but are not included
in your kit. The TIP connector circuit and pinout are shown in Figure 2-10.
