DATASHEET
Transmit Clock: 25MHz in 100Base-TX mode. 2.5MHz in
10Base-T mode.
Note:
Note:
Receive Data 0: Bit 0 of the 4 data bits that are sent by the PHY
in the receive path.
PHY Operating Mode Bit 0: set the default MODE of the PHY.
Note:
Receive Data 1: Bit 1 of the 4 data bits that are sent by the PHY
in the receive path.
PHY Operating Mode Bit 1: set the default MODE of the PHY.
Note:
Receive Data 2: Bit 2 of the 4 data bits that are sent by the PHY
in the receive path.
PHY Operating Mode Bit 2: set the default MODE of the PHY.
Notes:
Receive Data 3: Bit 3 of the 4 data bits that are sent by the PHY
in the receive path.
nINTSEL: On power-up or external reset, the mode of the
nINT/TXER/TXD4 pin is selected.
Notes:
RXD2 is not used in RMII Mode.
See
the MODE options.
When RXD3/nINTSEL is floated or pulled to VDDIO, nINT is
selected for operation on pin nINT/TXER/TXD4 (default).
When RXD3/nINTSEL is pulled low to VSS through a resistor,
(see
page
nINT/TXER/TXD4.
RXD3 is not used in RMII Mode
If the nINT/TXER/TXD4 pin is configured for nINT mode, then
a pull-up resistor is needed to VDDIO on the nINT/TXER/TXD4
pin. see

32.
This signal is not used in RMII Mode.
For proper TXCLK operation, RX_ER and RX_DV must
NOT be driven high externally on a hardware reset or
on a LAN8700 power up.
