15.2.3 HcFmNumber register (R/W: 0FH/8FH)
Table 50:
The HcFmNumber register is a 16-bit counter, and the bit allocation is given in
Table
The HCD may use the 16-bit value specified in this register and generate a 32-bit
frame number without requiring frequent access to the register.
Code (Hex): 0F — read

Description
FrameRemainingToggle: This bit is loaded from the
FrameIntervalToggle (FIT) field of HcFmInterval whenever
FrameRemaining (FR) reaches 0. This bit is used by the HCD for
synchronization between FrameInterval (FI) and FrameRemaining
(FR).
reserved
FrameRemaining: This counter is decremented at each bit time.
When it reaches zero, it is reset by loading the FrameInterval (FI)
value specified in HcFmInterval at the next bit time boundary.
When entering the USBOperational state, the HC reloads it with
the content of the FrameInterval (FI) part of the HcFmInterval
register and uses the updated value from the next SOF.
