checked on the audio IC.
(2) Fig. 2-3: Allows development and debugging using the client’s host CPU.
(3) Fig. 2-4: Allows operation checking and debugging of the audio IC board developed by the
client.
(3) Fig. 2-5: ROM with a built-in audio IC can be emulated by connecting the optional ROM
emulator.

.
For evaluations based on the configurations shown in Figures 3 and 4, fit a connector to suit the
client’s board to the “open” end of the cable provided. Clients using the board while connected to an
external host (Fig. 2-3) or an evaluation board host (Fig. 2-4) should contact Seiko Epson for detailed
