/*
* This function drives all the I/O's as output-low, to avoid floating inputs
* (which cause extra power to be consumed).  This setting is compatible with  
 * TI FET target boards, the F5529 Launchpad, and F5529 Experimenters Board;  
 * but may not be compatible with custom hardware, which may have components  
 * attached to the I/Os that could be affected by these settings.  So if using
* other boards, this function may need to be modified.
