HcLSThreshold Register
The HcLSThreshold register contains an 11-bit value used by the HC to determine
whether to commit to the transfer of a maximum of 8-byte LS packet before EOF.
Neither the HC nor the HCD is allowed to change this value.

FrameNumber:
This is incremented when HcFmRemaining is
reloaded. It will be rolled over to 0H after FFFFH. When the
USBOPERATIONAL state is entered, this will be incremented
automatically. HC will set the StartofFrame in HcInterruptStatus.

LSThreshold:
Contains a value that is compared to the
FrameRemaining field before a low-speed transaction is initiated.
The transaction is started only if FrameRemaining
this field. The
value is calculated by the HCD, which considers transmission and
setup overhead.
