This register contains a 14-bit value that indicates the bit time interval in a frame, that is,
between two consecutive SOFs, and a 15-bit value indicating the full-speed maximum
packet size that the Host Controller may transmit or receive, without causing a scheduling
overrun. The HCD may carry out minor adjustment on FI (Frame Interval) by writing a new
value over the present at each SOF. This provides the possibility for the Host Controller to
synchronize with an external clocking resource and to adjust any unknown local clock
offset. The bit allocation of the register is given in
Description
Done Head: When a TD is completed, the Host Controller writes the content of HcDoneHead to
the NextTD field of the TD. The Host Controller then overwrites the content of HcDoneHead
with the address of this TD. This is set to logic 0 whenever the Host Controller writes the
content of this register to HCCA.
