All bits can be set to one for every transfer. It species which
SOF the complete split needs to be sent. Valid only for IN.
Start split and complete split active bits,
SA = 0000 0001 and
SCS = 0000 0100, will cause SS to execute in Frame0 and
CS in
Frame2.

After processing
-
Species which
SOF the start split needs to be placed.
For OUT token: When the frame number of bits DW2[7:3]
matches the frame number of the USB bus, these bits are
checked for one before they are sent for the
SOF.
For IN token: Only
SOF0, SOF1, SOF2 or SOF3 can be
set to 1. Nothing can be set for
SOF4 and above.
