 * History:
 * $Log: ce.h,v $
 * Revision 1.6  2006/06/06 03:59:00  tvander
 * Updated battery test logic so it can use hardware timers as well as software timers.
 *
 * Revision 1.5  2006/03/08 00:08:01  tvander
 * Multiplexed interrupts are in io65xx.c
 * Added stubbed interrupt to io65xx.c
 * Clean build
 *
 * Revision 1.4  2006/01/10 04:04:59  gmikef
 * Added PDATA support for CE Outputs.
 *
 * Revision 1.3  2005/12/09 19:42:10  tvander
 * Calibration save and restore now work in flash, and save and restore temp_nom
 * in the 6520's temp_raw value for the CE variables.
 *
 * Revision 1.2  2005/09/22 23:45:14  tvander
