10.2.3 HcFmNumber register (R: 0FH)
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.
Code (Hex): 0F — read

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.
Description
reserved
FrameNumber: This field is incremented when HcFmRemaining
is reloaded. It rolls over to 0000H after FFFFH. When the
USBOperational state is entered, this field will be incremented
automatically. The HC will set bit StartofFrame in the
HcInterruptStatus register.
