The HcFmNumber register is a 16-bit counter, and the bit allocation is given in
provides a timing reference for events happening in the Host Controller 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.

HcFmInterval at the next bit time boundary. When entering the
USBOperational state, the Host Controller reloads it with the content of the
FrameInterval (FI) part of the HcFmInterval register and uses the updated
value from the next SOF.
