Configuration Descriptor
The Configuration Descriptor must be written to PE in the Configuration Descriptor format
(note for wTotalLength is provided below) specified in Universal Serial Bus Specification*
See the
‘
Sample Descriptors
’
section for the device descriptor samples.
As to wTotalLength, a sum of Configuration Descriptor size and Report Descriptor must
be configured.
For the Peripheral devices that uses both EP1 and EP3, a sum of the Configuration Descrip-
tor length and the Report Descriptor length corresponding to the EP must be configured.
NOTE:
*Universal Serial Bus Specification, Revision 1.0, January 15, 1996.
String Descriptor
String Descriptor will not be used in usual cases.
Report Descriptor
Report Descriptor must be written to PE in the Report Descriptor format specified in Uni-
versal Serial Bus Specification*. See the
‘
Sample Descriptor
’
section for the report descrip-
tor samples.
NOTE:
*Universal Serial Bus Specification, Revision 1.0, January 15, 1996.
