============================================================
CPU Production Firmware Version 1.3 release notes:

- This is the user loadable version of the Factory 1.3 CPU firmware.  
  Will display as "uP Appl Ver:U1.3" after loading and is identical to
  the factory "F1.3" load.

- Please use with DSP version 1.2 or higher, otherwise some features
  may not operate properly


New features:

- Added 'C' command to PC/IF protocol:
  STX 'C' <bitmap> ETX <sum>
  <bitmap>:   bit 0 = CCDump on=1, off=0
              bit 1 = DSPDump on=1, off=0
   These settings are temporary.  They're not written to the EEPROM
   Glob area.  A power cycle will revert to the EEPROM Glob settings.


Fixes / Enhancements:

- Fixed CCDump output for EDACS message pairs for 3rd party software
  compatibility.

- Improved reliability of the NAC display within the TSYS Analyze mode.

- Changed P25 TSYS Analyze LCD display to increase readability against 
  publicly available system data.  ("HHH" = Hex, "DDD" = Decimal):

  From: "Sys:HHH  RHH SHH"
  To:   "Sy:HHH RDDD SDDD"
