Description
FrameRemainingToggle (FRT)
This bit is always loaded from the FrameIntervalToggle bit in
HcFminterval when FrameReamining reaches 0. This bit is used
by HCD for the synchronization between FrameInterval and
FrameReamining.
Reserved.
FrameRemaining (FR)
This counter is decremented at each bit time. When this counter
reaches 0, this counter is reset by loading the value of the
FramInterval bit specified in the HcFminterval register at the
next bit time boundary. When the host controller transits to the
UsbOperational state, it read the FrameInterval bit in the
HcFminterval register again and use the updated value from the
next SOF.
