Amount of entries in the transmitter FIFO. The value of
this field ranges from 0 to FF_DATA_NR
(EZ_DATA_NR/2).

SR_VALID

Indicates whether the TX shift registers holds a valid
data frame ('1') or not ('0'). The shift register can be
considered the top of the TX FIFO (the data frame is
not included in the USED field of the TX FIFO). The
shift register is a working register and holds the data
frame that is currently transmitted (when the protocol
state machine is transmitting a data frame) or the data
frame that is transmitted next (when the protocol state
machine is not transmitting a data frame).
