4.2.3. SERIAL NUMBER

The XVF3510 allows a 24 ASCII character long serial number to be stored in the external flash memory.
This can be accessed using the VocalFusion Control application using the following commands
(XVF3510-INT shown for example). To write to the serial number register use:
vfctrl_i2c SET_SERIAL_NUMBER "DEADBEEF"
and to read use:
vfctrl_i2c GET_SERIAL_NUMBER
USB DEVICE ENUMERATION (XVF3510-UA ONLY)
The XVF3510-UA additionally allows the Serial Number to be copied into the iSerialNumber field of
the USB descriptor. As the host reads the USB descriptor on enumeration the command to copy the
serial number must be present in the a Data Partition. To illustrate this process the following commands
must be incorporated into a Data Partition in the specified order (example assumes SERIAL_NUMBER
field is already populated).
To set the USB configuration to use the serial number in the descriptor add the following lines, in this
order, to the Data Partition:
SET_USB_SERIAL_NUMBER 1
To set the USB configuration to start enumeration:
SET_USB_START_STATUS 1
