USB Descriptor Vendor ID

The Vendor ID returned in the GET DEVICE DESCRIPTOR command is contained in this register. The DSP can change the Vendor ID by writing to this register during the Serial EEPROM initialization. The default Vendor ID is 0x0456, which corresponds to Analog Devices, Inc.

V[15:0] = Vendor ID (default = 0x0456)

USB Descriptor Product ID

The Product ID returned in the GET DEVICE DESCRIPTOR command is contained in this register. The DSP can change the Product ID by writing to this register during the Serial EEPROM initialization. The default Product ID is 0x2192.

P[15:0] = Product ID (default = 0x2192)

USB Descriptor Release Number

The Release Number returned in the GET DEVICE DESCRIPTOR command is contained in this register. The DSP can change the Release Number by writing to this register during the Serial EEPROM initialization. The default Release Number is 0x0100, which corresponds to Version 01.00.

R[15:0] = Release Number (default = 0x0100)

USB Descriptor Device Attributes

The device-specific attributes returned in the GET DEVICE DESCRIPTOR command are contained in this register. The DSP can change the attributes by writing to this register during the Serial EEPROM initialization. The default attributes are 0x80FA, which correspond to bus-powered, no remote wake-up, and max power = 500 mA.

•SP: 1 = self-powered, 0 = bus-powered (default = 0)

•RW: 1 = have remote wake-up capability, 0 = no remote wake-up capability (default = 0)

•C[7:0] = power consumption from bus, expressed in 2 mA units (default = xFA 500 mA)

USB DSP MCU Register Definitions

MCU registers, described in Table 12, are defined in four memory spaces that are grouped by the following address ranges:

•0x0XXX—This address range defines general-purpose USB status and control registers

•0x1XXX—This address range defines registers that are specific to endpoint setup and control

•0x2XXX—This address range defines the registers used for REGIO accesses to the DSP register space

•0x3XXX—This address range defines the MCU program memory write address space
