IP175DLF-DS-R10.1 Pin description (continued) Pin No. Label Type Description External MII port setting 75 P4MII_SNI IPL SNI enable for MII0 1: SNI interface 0: MII interface (default). It is valid only is P4EXT is pulled high and RMII_EN is pulled low. It is valid for MII0 only. 51 MII1_DIS IPL Disable MII1 1: MII1 is disabled. It is for router application with one-MAC CPU. 0:.MII1 is enabled. PHY4 is an independent PHY and can be access through MII1. It is for router application with two-MAC CPU (default). It is valid only if P4EXT is pulled high.

RMII_EN takes precedence of P4MII_SNI. 2. In MAC mode application, MII_CLK must be provided before end of chip reset, otherwise must follow up a software-reset after MII_CLK be provided. 3. In RMII mode application, RMII_CLK must be provided before end of chip reset, otherwise must follow up a software-reset after RMII_CLK be provided. |
