Field Name
High-speed interval for polling (max NAK rate). Does not
apply to FS bulk endpoints, set to zero.
Length of this descriptor in bytes.
Endpoint descriptor type.
This is an In endpoint, endpoint number 2.
This is a bulk endpoint.
Max data transfer size.
High-speed interval for polling (max NAK rate). Does not
apply to FS bulk endpoints, set to zero.
Length of this descriptor in bytes.
Endpoint descriptor type.
This is an In endpoint, endpoint number 3.
This is an interrupt endpoint.
Max data transfer size.
High-speed interval for polling (max NAK rate).
Reserved.
LANGID descriptor length.
Descriptor type.
Language supported (0x0409 = US English). CY7C68310
only supports one language code
Length of Configuration descriptor in bytes.
Descriptor type.
Number of bytes returned in this configuration. This includes
the configuration descriptor plus all the interface and
endpoint descriptors.
Number of interfaces supported. The CY7C68310 only
supports one interface.
The value to use as an argument to Set Configuration to
select the configuration. This value must be set to 0x02.
Index to the configuration string. This entry must equal half
of the address value where the string starts or 0x00 if the
string does not exist.
Device attributes for this configuration. Configuration
characteristics:
Maximum power consumption for this configuration. Units
used are mA*2 (i.e., 0x31 = 98 mA, 0xF9 = 498 mA).
