002E 0200H
RCSEL
Loopback mode
Loopback between the transmit FIFO and receive FIFO is performed.
RXCLK selection
TXCLK is selected to be internally connected, instead of RXCLK.
Set this bit if it is necessary to change RXCLK to TXCLK when the MAC and the FIFO controller
are in the loopback mode.
Set these bits to “0000”.
