Enabling the SROM
The ADNS-3080 must operate from the externally loaded
programming. This architecture enables immediate
adoption of new features and improved performance
algorithms. The external program is supplied by Avago
as a file which may be burned into a programmable
device. A microcontroller with sufficient memory may be
used. On power-up and reset, the ADNS-3080 program is
downloaded into volatile memory using the burst-mode
procedure described in the Synchronous Serial Port
section. The program size is 1986 x 8 bits.
For more information, please refer to the ADNS-3080
datasheet.

Base Plate Feature – IGES File
The IGES file on the CD-ROM provides recommended
base plate molding features to ensure optical alignment.
This includes PCB­ assembly diagrams like solder fixture in
assembly and exploded view, as well as solder plate. See
Appendix D for details.
Reference Design Documentation – Gerber File
The Gerber File presents detailed schematics used in
ADNK-3083 in PCB­ layout form. See Appendix C for more
details.
Overall circuit
A schematic of the overall circuit is shown in Appendix A
of this document. Appendix B­ lists the bill of materials.
Firmware Implementation
The firmware for this reference design is written in the
Cypress assembly language. The following files are re-
quired to compile the mouse firmware 637xx.inc – the
CY7C63743-PXC I/O registers definition.
adns-3080.asm – main mouse firmware
macros.inc – general macros used with this design
ps2.inc – PS/2 interface constants
usb.inc – USB­ interface constants
adns-3080_srom_12.inc – SROM firmware
At power up, the firmware examines the host interface
and automatically determines if the mouse is plugged
into a USB­ or a PS/2 host connection. After the interface
type has been determined, the host firmware configures
itself to operate on the detected interface.
