ADSP-2192M

USB SETUP Token Command Register

This register is defined as eight bytes long and contains the data

sent on the USB from the most recent SETUP transaction. This

register is read by the MCU only.

USB SETUP Token Data Register

If the most recent SETUP transaction involves a data OUT stage,

this register is defined as eight bytes long and contains the data

sent on the USB during the data stage. This is also where the

MCU will write data to be sent in response to a SETUP transac-

tion involving a data IN stage. This register is read/write by the

MCU only.

USB SETUP Counter Register

This register provides information as the total size of the setup

transaction data stage. This register is read/write by the MCU

only.

• C[3:0] Total amount of data (bytes) to be sent/received

during the data stage of the SETUP transaction

USB Register I/O Address Register

This register contains the address of the ADSP-2192M register

that is to be read/written. This register is read/write by the MCU

only.

• A[15] Start ADSP-2192M read/write cycle

• A[14] 1 = WRITE, 0 = READ

• A[13:0] ADSP-2192M address to read/write

USB Register I/O Data Register

This register contains the data of the ADSP-2192M register

which has been read or is to be written. This register is read/write

by the MCU only.

• D[15:0] During READ this register contains the data

read from the ADSP-2192M; during WRITE this register

is the data to be written to the ADSP-2192M.

USB Control Register

This register controls various USB functions. This register is

read/write by the MCU only.

• MO 1 = MCU has completed boot sequence and is ready

to respond to USB commands

• DI 1 = Disconnect CONFIG device and enumerate again

using the downloaded MCU configuration

• BB 1 = After reset boot from MCU RAM; 0 = after reset

boot from MCU ROM

• INT = Active interrupt for the 8052 MCU

• ISE = Current interrupt is for a SETUP token

• IIN = Current interrupt is for an IN token

• IOU = Current interrupt is for an OUT token

• ER = Error in the current SETUP transaction. Generate

STALL condition on EP0.

USB Address/Endpoint Register

This register contains the USB address and active endpoint. This

register is read/write by the MCU only.

• A[6:0] USB address assigned to device

• EP[3:0] USB last active endpoint

USB Frame Number Register

This register contains the last USB frame number. This register

is read by the MCU only.

• FN[10:0] USB frame number

General USB Device Definitions

The following tables define the USB device descriptors: Table 13

describes the USB device descriptor; offset fields 8–13 are user-

definable via Serial EEPROM. Table 14 describes the USB

configuration descriptor; offset fields 7–8 are user-definable via

Serial EEPROM. Table 15, Table 16, and Table 17 describe the

USB string descriptor indexes.
