Indicates whether the RX shift registers holds a
(partial) valid data frame ('1') or not ('0'). The shift
register can be considered the bottom of the RX FIFO
(the data frame is not included in the USED field of the
RX FIFO). The shift register is a working register and
holds the data frame that is currently being received
(when the protocol state machine is receiving a data
frame).
