Member Data Documentation
TUint
iDir
Direction (mask: KUsbEpDirIn, etc., but used as value).
TInt
iExtra
The number of extra bytes that the standard endpoint descriptor should be extended by. In almost all cases, this should be 0 (zero).
TUint32
iFeatureWord1
32 flag bits indicating miscellaneous endpoint features. Currently defined are:
TInt
iInterval
Interval for polling full-speed interrupt and isochronous endpoints. Expressed either directly in milliseconds with a valid range 1..255 (interrupt), or for use as 'value' in the expression interval=2^(value-1) with a valid range 1..16 (isochronous).
TInt
iInterval_Hs
Interval for polling high-speed interrupt and isochronous endpoints, or to specify the NAK rate for high-speed control and bulk OUT endpoints. Expressed either for use as 'value' in the expression interval=2^(value-1) with a valid range 1..16 (interrupt and isochronous), or directly as the maximum NAK rate with a valid range 0..255 (control and bulk).
TInt
iSize
Maximum packet size (literal, no mask).
TInt
iTransactions
The number of additional transactions per uframe to be scheduled (0..2) (A value greater than zero is only valid for high-speed high bandwidth interrupt and isochronous endpoints. Also note that there are endpoint size restrictions associated with additional transactions - see 9.6.6.)
TUint
iType
Endpoint type (mask: KUsbEpTypeControl, etc., but used as value).
