 * $Log: wh.h,v $
 * Revision 1.14  2006/09/13 21:39:13  gmikef
 * *** empty log message ***
 *
 * Revision 1.13  2006/09/10 00:28:59  Michael T. Fischer
 * First version to support DGM0915 LCD.
 *
 * Revision 1.12  2006/09/09 01:15:09  gmikef
 * *** empty log message ***
 *
 * Revision 1.11  2006/09/08 07:38:14  Michael T. Fischer
 * *** empty log message ***
 *
 * Revision 1.10  2006/07/07 01:07:06  tvander
 * Made the brownout LCD format logic non-reentrant, and conditional on a new
 * compile flag, AUTOSLEEP
 *
 * Revision 1.9  2006/06/06 05:15:21  tvander
 * clean build
 *
 * Revision 1.8  2006/05/18 23:18:55  tvander
 * 16K and 32K
 * First cut at new requirements.
 * 32K 6521 is grossly tested.
 * All others have a clean compile with C51 8.02
 *
 * Revision 1.7  2006/04/27 00:06:58  tvander
 * Added tamper resistance, mostly to wh.c; Added a calibration signal to rtc.c
 *
 * Revision 1.6  2006/03/06 03:42:00  Michael T. Fischer
 * More 6530 prep.
 *
 * Revision 1.5  2006/02/10 03:13:22  tvander
 * Fixed VAh calculations and display, date display
 *
 * Revision 1.4  2006/01/10 04:08:53  gmikef
 * Added PDATA support for CE Outputs.
 *
 * Revision 1.2  2005/11/09 02:21:17  tvander
 * Added code to display watt hours from brownout mode.
 * Added code to clear EEPROM (lapie command "EEE")
 *
 * Revision 1.1  2005/10/08 04:41:29  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.
