The big question seems to be what the RefMan means when talking about<br>
the "system clock frequency". Obiously it is NOT the CPU clock as<br>
code variants above assume. The examples in "Table 17-24. Programming<br>
Examples for MII_SPEED Register" list "system clock frequencies" of<br>
25, 33, 40 and 50 MHz - which also indiocates that some other<br>
frequency might be referenced here.<br>
<br>
But which one is it?</blockquote><div><br>My best guess is still that it is ips clock. I think I stated in a previous email ipb, but I meant ips. 5200 has ibp and 5121 has ips. Have you looked at he MII clock on a scope to see how the calculated values compare to actual? <br>
