The MAC transmits data to the transceiver using
this signal in all modes.
The MAC transmits data to the transceiver using
this signal in all modes.
The MAC transmits data to the transceiver using
this signal in MII mode.
Note:
The MAC transmits data to the transceiver using
this signal in MII mode.
Note:
Active low interrupt output. Place an external
resistor pull-up to VDDIO.
Note:
Note:
When driven high, the 4B/5B encode process
substitutes the Transmit Error code-group (/H/)
for the encoded data word. This input is ignored
in the 10BASE-T mode of operation.
In Symbol Interface (5B decoding) mode, this
signal becomes the MII Transmit Data 4 line (the
MSB of the 5-bit symbol code-group).
Note:
Indicates that valid transmission data is present
on TXD[3:0]. In RMII mode, only TXD[1:0]
provide valid data.
Used to latch data from the MAC into the
transceiver.
Note:
MII (100BASE-TX): 25 MHz
MII (10BASE-T): 2.5 MHz
