Description
For MII MAC mode, this pin represents MRXC/MII receive clock (acts
as input).
For MII/SNI PHY mode, this pin represent PTXC/MII transmit clock
(acts as output).
For MII MAC mode, this pin represents MCOL, MII collision detect
(acts as input).
For MII/SNI PHY mode, this pin represents PCOL, MII collision detect
(acts as output).
Output after reset.
For MII MAC mode, these pins are MTXD[3:0], MII transmit data of
MAC.
For MII PHY mode, these pins are PRXD[3:0], MII receive data of
MAC.
For SNI PHY mode, PRXD[0] is SNI serial receive data. PRXD[3:1]
are unused.
For MII MAC mode, this pin represents MTXEN, MII transmit enable.
For MII PHY mode, this pin represents PRXDV, MII receive data valid.
For SNI PHY mode, this pin represents PRXDV, SNI receive data
valid.
For MII MAC mode, this pin represents MTXC, MII transmit clock
(acts as input).
For MII/SNI PHY mode, this pin represents MRXC, MII/SNI receive
clock (acts as output).
Input upon reset = Select MII port (9
th
port) operating mode.
11=Tristate MII output.
10=MII MAC mode.
01=MII PHY mode.
00=SNI PHY mode.
Provides MII port (9
th
port) Link Status for MAC module at MII
MAC/MII PHY/SNI PHY operation mode in real time.
This pin sets the link status of the MII port MAC module in real-time.
Provides MII port (9
th
port) duplex status for MAC module at MII
MAC/MII PHY/SNI PHY operation mode in real time.
1: MII port operates in full duplex mode
0: MII port operates in half duplex mode
Provides MII port (9
th
port) speed status for MAC module at MII
MAC/MII PHY/SNI PHY operation mode in real time.
1: MII port operates at 100Mbps speed
0: MII port operates at 10Mbps speed
In an application outlined below, this pin should be left floating:
For HomePNA (MII MAC mode), speed is determined by RXC and
TXC from PHY of HomePNA running at 1Mbps.
For SNI PHY mode, speed is fixed at 10MHz clock rate.
Provides MII port (9
th
port) flow control status for MAC module at MII
MAC/MII PHY/SNI PHY operation mode in real time.
1: MII port has flow control ability
0: MII port does not have flow control ability
