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.
