RX Status FIFO Used Space (RXSUSED)
This field indicates the amount of space, in DWORD’s, currently used in the
RX Status FIFO.
RX Data FIFO Used Space (RXDUSED)
This field indicates the amount of space, in bytes, used in the RX Data FIFO.
For each receive frame, the field is incremented by the length of the receive
data. In cases where the payload does not end on a DWORD boundary, the
total will be rounded up to the nearest DWORD.
RX FIFO Information Register (RX_FIFO_INF)
This register contains the indication of used space in the RX FIFO’s.
