//  DESCRIPTION: 71M652x POWER METER - battery test code.
//  If BME, bit 6 of 0x2020, is set, then a load is applied and on the
//  next alternate conversion cycle, the battery voltage is measured.
//  Since this loads the battery, it should be as short as possible,
//  and done only rarely, e.g. once per day.
//  Therefore, the real-time logic is in the CE interrupts in ce.c
//  In xfer_busy, which starts the almux cycle to mesure temperature,
//  there's code to start a battery test.  In ce-busy, which runs
//  after every mux cycle, there's code to collect the battery test
//  data.
//  The code here commands the battery test, and then interprets it.
//

 * History
 * $Log: battest.h,v $
 * Revision 1.4  2006/06/14 02:41:26  tvander
 * New, derated battery test runs at 1/8 MPU speed, but uses 150x more battery
 * current.
 *
 * Revision 1.3  2006/06/06 03:57:33  tvander
 * Modified to run with hardware timers as well as software timers.
 *
 * Revision 1.2  2006/05/18 23:18:50  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 1.1  2006/05/17 19:07:59  tvander
 * Battery test works.
 * Power factor works for instantaneous value.  Periodic value compiles, but is
 * untested.
