149 / 280 page  7.10.5 Peripherals 7.10.5.1 CPSW3G For more details about features and additional description information on the device Gigabit Ethernet MAC, see the corresponding subsections within Signal Descriptions and Detailed Description sections. Note CPSW3G MDIO0, CPSW3G RMII1, CPSW3G RMII2, and CPSW3G RGMII1 have one or more signals which can be multiplexed to more than one pin. Timing requirements and switching characteristics defined in this section are only valid for specific pin combinations known as IOSETs. Valid pin combinations or IOSETs for these interfaces can be found in the tables of the CPSW3G IOSETs section. 7.10.5.1.1 CPSW3G MDIO Timing Table 7-19, Table 7-20, Table 7-21, and Figure 7-22 present timing conditions, requirements, and switching characteristics for CPSW3G MDIO.
