3.4.6 TDM Interface Related Pins
Table 69 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 69 for those signals that are not selected. Table 69
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.

2. In case of subset of TDM interface usage please make sure to disable unused TDM modules. See Chapter 20, TDM, in the
MSC8144EC Reference Manual for details.
3.4.7 PCI Related Pins
Table 70 lists the board connections of the pins when PCI is not used. Table 70 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.
