Subject: [oc] Question on Ethernet MAC 10/100 Mbps
I thought MII Management does both, it can be used to write to PHY
and ready from PHY.
that's what it says in the spec, so I am assuming that I can read from
phy and store in MIIM and use the BD to transmit the data from MIIM to
the external memory(Host Interface).
tell me if that is wrong
thanks
