3.5.3
RGMII Ethernet Related Pins
Note:
Table 46 and Table 47 assume that the alternate function of the specified pin is not used. If the alternate function is
used, connect the pin as required to support that function.
GE_MDC and GE_MDIO pins should be connected as required by the specified protocol. If neither GE1 nor GE2 is used,
Table 47 lists the recommended management pin connections.
3.5.4
TDM Interface Related Pins
Table 48 lists the board connections of the TDM pins when an entire specific TDM is not used. For multiplexing options that
select a subset of a TDM interface, use the connections described in Table 48 for those signals that are not selected. Table 48
assumes that the alternate function of the specified pin is not used. If the alternate function is used, connect that pin as required
to support the selected function.
