FRNUM: Frame Number Register
Bits [10:0] of this register contain the current frame number which is included in the
frame SOF packet. This register reflects the count value of the internal frame number
counter. Bits [9:0] are used to select a particular entry in the Frame List during
schedule execution. This register is updated at the end of each frame time.
This register must be written as a word. Byte writes are not supported. This register
cannot be written unless the Host Controller is in the STOPPED state as indicated by the
HCHalted bit (USBSTS register). A write to this register while the Run/Stop bit is set
(USBCMD register) is ignored.

Frame List Current Index/Frame Number: Bits
[10:0] provide the frame number in the SOF Frame. The
value in this register increments at the end of each time
frame (approximately every 1 ms). In addition, bits
[9:0] are used for the Frame List current index and
correspond to memory address signals [11:2].
