15 / 66 page ![]() USB 2.0 to 10/100 Ethernet Controller Datasheet SMSC LAN950x Family 15 Revision 1.1 (04-18-13) DATASHEET 1 Transmit Data 2 (External PHY Mode) TXD2 O8 (PD) In external PHY mode, this pin functions as the transmit data 2 output to the external PHY. General Purpose I/O 6 (Internal PHY Mode Only) GPIO6 IS/O8/ OD8 (PU) This General Purpose I/O pin is fully programmable as either a push-pull output, an open-drain output, or a Schmitt-triggered input. USB Port Swap Configuration Strap PORT_SWAP IS (PD) Swaps the mapping of USBDP and USBDM. 0 = USBDP maps to the USB D+ line and USBDM maps to the USB D- line. 1 = USBDP maps to the USB D- line. USBDM maps to the USB D+ line. See Note 3.1 for more information on configuration straps. 1 Transmit Data 1 (External PHY Mode) TXD1 O8 (PD) In external PHY mode, this pin functions as the transmit data 1 output to the external PHY. General Purpose I/O 5 (Internal PHY Mode Only) GPIO5 IS/O8/ OD8 (PU) This General Purpose I/O pin is fully programmable as either a push-pull output, an open-drain output, or a Schmitt-triggered input. Remote Wakeup Configuration Strap RMT_WKP IS (PD) This strap configures the default descriptor values to support remote wakeup. 0 = Remote wakeup is not supported. 1 = Remote wakeup is supported. See Note 3.1 for more information on configuration straps. Table 3.1 MII Interface Pins (continued) NUM PINS NAME SYMBOL BUFFER TYPE DESCRIPTION |
