In Full speed mode, this field contains the 8 high-order bits of the 16-bit internal frame counter (at 30MHz, counter length is
30000 to ensure a SOF generation every 1 ms).
In High speed mode, this field contains the 8 high-order bits of the 16-bit internal frame counter (at 30MHz, counter length is
3750 to ensure a SOF generation every 125 us).
This field contains the current SOF number.
This field can be written. In this case, the MFNUM field is reset to zero.
This field contains the current Micro Frame number (can vary from 0 to 7) updated every 125us.
When operating in full-speed mode, this field is tied to zero.
