/***************************************************************************
 * History:
 * $Log: meter.h,v $
 * Revision 1.47  2006/03/10 00:06:26  tvander
 * Remove unused pulse-counting variables.
 *
 * Revision 1.46  2006/10/06 01:42:28  tvander
 * The calibration count is moved into the nonvolatile accumulators.
 * A dummy was left so that the addresses in between are unchanged.
 *
 * Revision 1.45  2006/10/03 00:35:38  tvander
 * Moved main_edge_cnt_nom earlier in the data structures, before deltaT, the start of the 32-bit indexing.  In that way, it does not offset the indexing by one byte, a clear error.
 *
 * Revision 1.44  2006/09/27 01:35:56  tvander
 * Removed CFG_BATTERY from the software configuration
 *
 * Revision 1.43  2006/09/14 00:39:25  tvander
 * defines vasum
 *
 * Revision 1.42  2006/09/12 02:45:02  gmikef
 * *** empty log message ***
 *
 * Revision 1.41  2006/09/09 02:29:40  gmikef
 * *** empty log message ***

 * Split out scrolling function.
 *
 * Revision 1.37  2006/07/27 00:58:01  tvander
 * Fixed code to lock RTC to line frequency.  Added a single byte to the shared
 * data structure.
 *
 * Revision 1.36  2006/07/25 00:30:02  tvander
 * Main edge count needs to be signed.
 *
 * Revision 1.35  2006/07/07 22:18:44  tvander
 * Saves brownout cache data.
 *
 * Revision 1.34  2006/07/07 01:05:45  tvander
 * Added a battery-present configuration bit to r_Parms.T_Config
 *
 * Revision 1.33  2006/06/09 22:40:55  tvander
 * Redesigned creep to operate on voltages as well as current, and to account
 * correctly for the equations.
 *
 * Revision 1.32  2006/06/08 20:59:18  tvander
 * Added sum variables for Wh and VARh net-metering
 *
 * Revision 1.31  2006/06/06 05:15:20  tvander
 * clean build
 *
 * Revision 1.30  2006/05/25 03:31:45  tvander
 * Renamed variables so nonvolatile variables can be switched to other definitions
 * of watt-hours (e.g. from absolute value to volt-amps or imports)
 * (meter.c, meter.h, pulse_src.c)
 * FIxed power factors so they zero correctly.
 * Fixed RMS to work with different accumulation interval.
 *
 * Revision 1.29  2006/05/18 23:18:52  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 1.28  2006/04/27 00:06:57  tvander
 * Added tamper resistance, mostly to wh.c; Added a calibration signal to rtc.c
 *
 * Revision 1.27  2006/04/25 01:09:55  tvander
 * Integrated improved RTC.  Compensates for time off, has default constant
 * compensation.  Computes true hours of operation.
 *
 * Revision 1.26  2006/04/19 01:16:41  tvander
 * Now defines where rtc.c puts its data.
 *
 * Revision 1.25  2006/04/12 00:27:49  tvander
 * Debugged compilation with equations 3 and 4, on 6513
 *
 * Revision 1.24  2006/03/31 23:40:09  tvander
 * IMAX2 modification
 *
 * Revision 1.23  2006/03/17 00:41:17  tvander
 * Reformatted Parameters_t to fit in IMAX2 stuff
 *
 * Revision 1.22  2006/03/06 03:39:43  Michael T. Fischer
 * More 6530 prep.
 *
 * Revision 1.21  2006/02/10 00:49:46  tvander
 * Added )1=2, count of accumulation intervals, reduced RAM usage by
 * making optional phase c, net metering, and pulse counts.
 * rearranged RAM so these things change in some reasonable way when accessed
 * by ).
 *
 * Revision 1.20  2006/02/08 03:43:27  tvander
 * Made "import" the default power measurement mode, rather than net-metering
 *
 * Revision 1.19  2006/01/25 01:05:14  tvander
 * Floating point temperature calibration
 *
 * Revision 1.18  2006/01/10 04:07:34  gmikef
 * Added PDATA support for CE Outputs.
 *
 * Revision 1.17  2006/01/04 04:47:52  gmikef
 * Switched RMS and VA calculations to use floating point. (and Calibration).
 *
 * Revision 1.16  2005/12/23 01:27:46  tvander
 * Meter.c would not compile for 6513 because a table was wrong.

 * 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.
 *

 * Release 6521 CLI version for early customers.
 * RMS works.
 * Accumulation interval to 1 second.
 * Wrate slowed to 3.2 Kh/pulse for new accumulation interval.
