Meaning of StartFrame value in KISO_CONTEXT on Isochronous-In-Transfer

[Ekkehard]

Hello,
I am in doubt about the meaning of StartFrame value in KISO_CONTEXT on In-Transfer.
In my case on reading iso packets (128KByte in one call) the value is incremented by 16 from one iso packet to the next, regardless of the preselected data rate (e.g. 1, 2 or 3 1024Byte packet per microframe).
Any ideas?

Best regards
Ekkehard

Sorry my fault, packetsize changed (and therefore possible datarate increases), and the time remains stable.
So forget the stuff :-)
