Miscellaneous Pins
Table 49 lists the board connections for the pins not required by the system design. Table 49 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.
Note:
For details on configuration, see the MSC8254 Reference Manual. For additional information, refer to the MSC815x
and MSC825x DSP Family Design Checklist.
