Function
Transmit Data.
Nibble-wide transmit data stream in MII mode. These four
bits are synchronous to the rising edge of TXCLK and
TXD[3] is the most significant bit
Di-bits Transmit Data.
TXD0 and TXD1 for the di-bits that are transmitted and are
driven synchronously to REFCLK. TXD[1] is the MSB. Note
that in 100Mb/s mode, TXD can change once per REFCLK
cycle, whereas in 10Mb/s mode, TXD must be held steady
for 10 consecutive REFCLK cycles. TXD[3] and TXD[2] are
not used in RMII Mode, left unconnected or pull down
externally for normal operation.
Serial Transmit Data.
TXD0 for the designated port inputs the data that is
transmitted and is driven synchronously to TXCLK in
10Mb/s mode. When ADM7001 is programmed into GPSI
mode, TXD[3:1] should be left unconnected or pull down
externally for normal operation.
Transmit Enable.
Transmit Enable to indicate that the data on TXD[3:0] is
valid.
Transmit Enable.
TXEN indicates that the di-bit on TXD is valid and it is driven
synchronously to REFCLK.
Transmit Enable.
Transmit Enable to indicate that the data on TXD0 is valid.
Transmit Error.
Active high signal to indicate that there is error condition
requested by MAC.
Transmit Error.
Active high signal to indicate that there is error condition
requested by MAC.
Keep Low in GPSI Mode.
