// WD MANAGEMENT-- defines software watchdogs: all software watchdogs
// must be reset before the hardware watchdog can be reset.
// Watchdog code is active only for watchdogs that are defined.
// Currently only the main loop (main.c) and periodic interrupts
// (tmr0.c, tmr1.c, ce.c) have watchdog code to enable.

 * $Log: wd.h,v $
 * Revision 1.7  2006/10/13 00:52:35  tvander
 * Removed compile options for 6530, 6515;
 * renamed 6511 and 6513 to trace11 and trace13;
 * Binary verified unchanged from previous version.
 *
 * Revision 1.6  2006/09/09 01:16:09  gmikef
 * *** empty log message ***
 *
 * Revision 1.5  2006/07/08 01:53:53  tvander
 * Detects invalid configurations
 *
 * Revision 1.4  2006/03/03 11:31:56  Michael T. Fischer
 * Prep for 6530 LCD, etc.
 *
 * Revision 1.2  2005/11/29 01:28:31  tvander
 * Software watchdogs actually work now.
 * Automatically enable software watchdogs by defining constant in wd.h
 * Optimized software watchdogs so they work faster.
 * Reset the watchdog is reset as soon as the enabling software watchdog is reset.
 * Removed the software watchdog test routine.
 *
 * Revision 1.1  2005/10/08 04:41:33  tvander
 * Fixed priority inversion.
 * Rewrote watchdog to work in brownout, but of course it doesn't work.
 * Watchdog can now be defeated by clearing watchdog option to 0.
 * Reorganized watt hour modules (at last!).
 * Disabled reading of STATUS in 6521_cli because the CE's status is always SAG.
 * Tested with 6521_CLI; measurements seem to work.
 * Fixed other builds.
 *
 * Revision 1.6  2005/09/22 23:45:25  tvander
 * Clean build all models and unit tests, updated copyright to be fore Teridian
 *
 * Revision 1.5  2005/09/11 00:34:08  tvander
 * Clean compiles
 *
 * Revision 1.4  2005/05/02 18:21:32  gmikef
 * *** empty log message ***
 *
 * Revision 1.4  2005/04/30 01:57:38  gmikef
 * *** empty log message ***
 *
 * Revision 1.2  2005/04/28 19:19:23  tvander
 * Added 651x stuff, comments, events.c interface (?)
