*<strong>Note</strong>4-1:<br />
The TXCT and RXCT pins of the magnetic with Au<strong>to</strong>-MDIX<br />
function should already be connected <strong>to</strong>gether inside.<br />
The TXCT and RXCT pins of the magnetic without Au<strong>to</strong>-MDIX<br />
function should be separate, these two pins should be<br />
short <strong>to</strong>gether on your schematic.<br />
*<strong>Note</strong>4-3:<br />
The AX88742 PHY <strong>Port</strong> 0/<strong>Port</strong> 1 LED display modes can be set<br />
by the AX88742 LED Control Register (LCR, address 0x0DC).<br />
<strong>Please</strong> <strong>refer</strong> <strong>to</strong> Section 5.2.18 of AX88742 datasheet for<br />
more details.<br />
B<br />
*<strong>Note</strong>4-2:<br />
The <strong>refer</strong>ence transformer of AX88742 demo board is<br />
YL2J201 Single RJ-45 Connec<strong>to</strong>r Module with<br />
Integrated 10/100 Base-TX Magnetics<br />
(Turns Ratio is 1CT:1CT with Au<strong>to</strong>-MDIX).<br />
