PRODUCTION DATA.
The three-port gigabit ethernet switch subsystem (GMAC_SW) provides ethernet packet communication and can be configured as an ethernet switch. It provides the Gigabit Media Independent Interface (G/MII) in MII mode, Reduced Gigabit Media Independent Interface (RGMII), Reduced Media Independent Interface (RMII), and the Management Data Input/Output (MDIO) for physical layer device (PHY) management.
NOTE
For more information, see the Ethernet Subsystem section of the Device TRM.
NOTE
The Gigabit, Reduced and Media Independent Interface n (n = 0 to 1) are also referred to as MIIn, RMIIn and RGMIIn.
CAUTION
The I/O timings provided in this section are valid only if signals within a single IOSET are used. The IOSETs are defined in Table 7-71, Table 7-74, Table 7-79 and Table 7-86.
CAUTION
The I/O Timings provided in this section are valid only for some GMAC usage modes when the corresponding Virtual I/O Timings or Manual I/O Timings are configured as described in the tables found in this section.
Table 7-67 and Figure 7-51 present timing requirements for MIIn in receive operation.
