23.3.25 USB Request Value Register (USBVAL)
USBVAL is a register that stores setup requests for control transfers. When the peripheral
controller function is selected, the value of wValue that has been received is stored. When the host
controller function is selected, the value of wValue to be transmitted is set.
This register is initialized by a power-on reset, a software reset, or a USB bus reset.

These bits store the USB request wValue value.
Note: When the function controller function is selected, these bits can only be read. When the
host controller function is selected, these bits can be read or written to.
