ic_rx_cell_max
5:0
RW If the cell fill of the RX SAR output FIFO becomes greater than this
value, cells from the port C input FIFO will be blocked. 3Fh = no
backpressure

9:6
RW If the cell fill of the port A output FIFO becomes greater than this value,
cells from the port C input FIFO will be blocked. Fh = no backpressure
ic_ob_cell_max
13:10
RW If the cell fill of the port B output FIFO becomes greater than this value,
cells from the port C input FIFO will be blocked. Fh = no backpressure
