SOFTWARE PREPARATION
The TCOM is not a stand alone board. It should be connected to the MPC8260ADS. To select the desired
configuration and ensure proper operation of the MPC8260TCOM board, changes in the MPC8260 GPIO
configuration may be required. The following table describes the different configurations of all the modules
on the board.
NOTE:
The FE modules have no H/W protection. Before using one of the FE module make sure that other modules
using the same GPIO are disabled. The following table shows the various types of communication
channels that can be implemented by connecting the TCOM & ADS cards.
The I/O are related to the MPC8260.
The dark column are the modules on the ADS.
