1.2 Initial Release
1.3 RFDA2026, RFDA0026, RFDA2046 added
1.4 Two atten widows are implemnted for RFDA0066, RFDA0056, RFDA0066 added
1.5 Last maintained by SK
1.6 Added new families of atten IC's requiriing flexible serial words (3513, 3613, etc)
1.7 Added RFAC3613 vari-cap part
1.71 Bug fix for 3715-P to drive LE high 
1.72 DBase corrected for RFSA3613
1.8.1 Added RFDA2125
1.8.2 Bug fix for RFSA2714-P t0 drive LE high.  
      Allows use of other parts database names (primarily to allow for including the revision date in the name)
1.8.3 Added provision to clock on rising or falling edge.  
      Database definiton now uses "Serial - Rising" or "Serial - Falling" to indicate which is used.
      Added case select for proper labels for new "QPC" part numbers. 
      Fixed control panel bug where SW1 buttons were not available in RFAC3612 selections. 
      Fixed bug with RFSA2614 control logic. 
1.8.4 Added:  QPC6614, QPC3213, QPC3223
1.9.0 Added: RFAC3622, RFAC3632, RFAC3642, RFSA4033, RFDA4005
      Major code changes to accomodate the new parts include: 
	- Expanded database fields for better labeling flexibility
	- Add 2 more switch option (currently only available in serial mode)
	- Added parts add/edit form for easier database maintenance
	- Removed hard-coded bandaids except for serial bit-shifting (RFSA3513, RFSA3613).
	- Split definition and function of dual attenuator windows.  Can now define number of bits independently. 
	- Parallel mode bit-shifts automatically if LSB(s) is not used (Ex: RFSA2614). 
	- Deleted BitStep field.  Only need to enter min and max values (indepently for both control boxes - enter zeros in the second box if not used)
1.9.1   - Fixed LE logic to stop inverting the expected clock logic from what was coded. (was previously inverting the clock for MSB-first SPI's
	- Fixed the Database to show all clock logic as rising edge.  Left in provision to invert clock for future use
	- Added RFSA2532 (required another bit-shift bandaid similar to RFSA2513)
	
1.9.2	- Added support for RFSA3623, RFSA3413, QPC6713.  
        - Added conditional logic to provide a leading LE pulse for RFAC36xx parts that require it.

1.9.3   - Added series and shunt provisions for RFAC3622, 32, and 42 EVB's
	- Changed RFAC's to Falling Edge in the database
	- Simplified clock-data array logic
