23.3.24 USB Request Type Register (USBREQ)
USBREQ is a register that stores setup requests for control transfers. When the function controller
function is selected, the values of bRequest and bmRequestType that have been received are
stored. When the host controller function is selected, the values of bRequest and bmRequestType
to be transmitted are set.
This register is initialized by a power-on reset, software reset, or a USB bus reset.
