21.3.15 Frame Remaining Register (HcFmRemaining)
HcFmRemaining contains a 14-bit down-counter that indicates bit times remaining until the
current frame is complete. HcFmRemaining is a read-only register. Operation is not guaranteed
when writing.

Description
Frame Remaining Toggle
When FR reaches H'0000, this bit stores the FIT
value in HcFmInterval.
This bit is used by HCD for the synchronization
between the FI and FR bits.
Reserved
These bits are always read as 0.
Frame Bit Times Remaining
This counter is decremented at each bit time. When
it reaches zero, it is re-set to the FI value in
HcFmInterval that is loaded at the next bit time
boundary. When entering the USB operational state,
HC re-loads the contents of the FI bit in
HcFmInterval to this counter and uses the updated
value from the next SOF.
