8 / 82 page LAN88730 DS60001256B-page 8 2012-2015 Microchip Technology Inc. 1 Receive Data 1 RXD1 VO8 Bit 1 of the 4 (2 in RMII mode) data bits that are sent by the transceiver on the receive path. PHY Operat- ing Mode 1 Configuration Strap MODE1 VIS (PU) Combined with MODE0 and MODE2, this configu- ration strap sets the default PHY mode. See Note 1 for more information on configuration straps. Note: Refer to Section 3.7.2, "MODE[2:0]: Mode Configuration" for additional details. 1 Receive Data 2 (MII Mode) RXD2 VO8 Bit 2 of the 4 (in MII mode) data bits that are sent by the transceiver on the receive path. Note: This signal is not used in RMII mode. MII/RMII Mode Select Configu- ration Strap RMIISEL VIS (PD) This configuration strap selects the MII or RMII mode of operation. When strapped low to VSS, MII mode is selected. When strapped high to VDDIO RMII mode is selected. See Note 1 for more information on configuration straps. Note: Refer to Section 3.7.3, "RMIISEL: MII/RMII Mode Configuration" for addi- tional details. 1 Receive Data 3 (MII Mode) RXD3 VO8 Bit 3 of the 4 (in MII mode) data bits that are sent by the transceiver on the receive path. Note: This signal is not used in RMII mode. PHY Address 2 Configuration Strap PHYAD2 VIS (PD) Combined with PHYAD0 and PHYAD1, this config- uration strap sets the transceiver’s SMI address. See Note 1 for more information on configuration straps. Note: Refer to Section 3.7.1, "PHYAD[2:0]: PHY Address Configuration" for addi- tional information. 1 Receive Error RXER VO8 This signal is asserted to indicate that an error was detected somewhere in the frame presently being transferred from the transceiver. Note: This signal is optional in RMII mode. Receive Data 4 (MII Mode) RXD4 VO8 In Symbol Interface (5B decoding) mode, this sig- nal is the MII Receive Data 4 signal, the MSB of the received 5-bit symbol code-group. Note: Unless configured to the Symbol Inter- face mode, this pin functions as RXER. PHY Address 0 Configuration Strap PHYAD0 VIS (PD) Combined with PHYAD1 and PHYAD2, this config- uration strap sets the transceiver’s SMI address. See Note 1 for more information on configuration straps. Note: Refer to Section 3.7.1, "PHYAD[2:0]: PHY Address Configuration" for addi- tional information.
