10.2.3 HcFmNumber register (R: 0FH)
reserved
Table 23:
The HcFmNumber register is a 16-bit counter. It provides a timing reference for
events happening in the HC and the HCD. 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.

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