Writing a one to this bit will allow the USBB to perform infinite IN requests when the Pipe is not frozen.
Writing a zero to this bit will perform a pre-defined number of IN requests. This number is the INRQ field.
This field contains the number of IN transactions before the USBB freezes the pipe. The USBB will perform (INRQ+1) IN
requests before to freeze the Pipe. This counter is automatically decreased by 1 each time a IN request has been successfully
performed.
This register has no effect when the INMODE bit is one (infinite IN requests generation till the pipe is not frozen).
