ADSP-219x/2192 DSP Hardware Reference B-71
ADSP-2192 DSP Peripheral Registers
USB DSP Registers
Overview
The USB registers control the USB interface, specifically the operation
and configuration of the USB Interface. Most of these registers are accessi-
ble only via the USB Bus, although a subset is accessible to the DSP.
The ADSP-2192 USB allows you to configure and attach a single device
with multiple interfaces and various endpoint configurations. The advan-
tages to this design are:
• Programmable descriptors and class specific command interpreter.
An MCU is supported on board, which allows you to soft download
different configurations and support any number of standard or
class specific commands.
• Eight user defined endpoints are provided. Endpoints can be con-
figured as either
BULK
,
ISO
, or
INT
and can be grouped and assigned to
any interface.
