15.2.4 HcLSThreshold register (R/W: 11H/91H)
Table 52:
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 the EOF.
Neither the HC nor the HCD is allowed to change this value.

Description
reserved
FrameNumber: This is incremented when HcFmRemaining is
reloaded. It needs to be rolled over to 0H after FFFFH. When the
USBOperational state is entered, this is incremented automatically.
The content needs to be written to HCCA after the HC has
incremented the FrameNumber (FN) at each frame boundary and
sent an SOF. However, the content needs to be written before
the HC reads the first Endpoint Descriptor (ED) in that frame. After
writing to HCCA, the HC needs to set the StartofFrame (SF) in
HcInterruptStatus.
Description
reserved
LSThreshold: Contains a value that is compared to the
FrameRemaining (FR) field before a low-speed transaction is
initiated. The transaction is started only if FrameRemaining
(FR)
considers transmission and set-up overhead.
