  16f83,  16cr83
  16c84,  16f84,   16cr84

  16f873, 16f876    - No Analog, PWM, Serial I/O
  16f874, 16f877    - No Analog, PWM, Serial I/O, Port D/E
  

• The assembler can generate both 12 and 14 bit opcodes.
• Non-contiguous instruction addresses are supported. (A program can have multiple ORG addresses)
• New Assembly commands to improve MPASM compatibility:
  PROCESSOR - Processor type can be specified from list above
  CONSTANT - One or more constant parameters can be specified
  VARIABLE - One or more variable parameters can be specified
  LOCAL command now supports multiple values and assignments
  New number formats .nnn (decimal) and 0nnnh (hexadecimal)
  Improved error reporting
• User preferences dialog has many more options
• Preferences and Plugins settings are saved by miSim when you Quit - no need to edit the settings file by hand!
• Plugins can specify how their config data is edited and displayed. This means that you don't have to edit the config string directly for newer plugins.
• New breadboard plugin supports and correctly displays all simulated processors.
• Plugins can be grouped into 'circuits'. Each circuit specifies a list of plugins and their configuration. A circuit can be 'opened' in one go, setting up all of the plugins for a particular project.
• If your programmer has a command line interface you can call it from within miSim without having to save .hex files or start the programmer application yourself.
• miSim DE can now let you know what upgrades and new Plugins are available. Select the upgrades you wish to install, and miSim downloads them, installs them and updates the settings file automatically.
• Text editor windows are more responsive
• GUI improvements - graphical controls 'stop', 'start' etc.
• Main Tab window has graphical tabs to click, instead of buttons
• Many bug fixes and other minor improvements

The previous version of the software was 1.7.7 Changes in this version are:

• New release format has simpler web pages included in download
• Manual pages split out of release for smaller download
• Class files removed from release - only .jar and .cab files are needed
• Individual processor implementation replaced by family, so related devices can be easily supported
• Added __CONFIG command to processor
• Config word and ID locations are properly stored and saved from processor
• EEProm Write Interrupt is emulated, EEProm write bugs cleared up
• Watchdog timer is implemented, along with full emulation of SLEEP and CLRWDT instructions
• Assembler reports warnings for data and parameters that have incorrect bit widths
• ResetListener interface allows Plugins to respond to processor reset
• getImage method retrieves images (and miSim logo) from .jar or .cab files where possible
• Bug fixes as usual

• All new Macro Assembler, fully integrated with editor
• Graphical display of errors and breakpoints
• Significantly faster assembly
• Variable and constant labels are supported (SET and EQU)
• All of the maths operators in MPLAB are supported
  • + - * / % & | ^ ++ -- << >> && ||
  • == >= > != < <=
  • = += *= /= -= %= <<= >>= &= |= ^=
• Conditional assembly is supported (IF, ELSE, ENDIF)
• Defined labels (#DEFINE), and conditionals work (IFDEF, IFNDEF)
• List control works (LIST, NOLIST)
• Numeric literals are much more compatible with MPASM
  • Hex: 0x0F, H'0F' Dec: 123, D'123'
  • Bin: B'11100101' Oct: O'1762'
  • Ascii: A'w', 'w'
  • $ = Current program counter
• Assembly reports all errors encountered, instead of stopping at the first one
• Errors are shown in the editor, Ctrl-N and Ctrl-P step through the Next and Previous errors
• The Assembled View window uses the same syntax aware display as the editor, so you get full syntax highlighting
• Macro assembly, supporting Macros with parameters and macro recursion
• Include files (INCLUDE)
• Binary load/disassembler uses the improved syntax highlighting View

• More sensible start up defaults
• Bug fixes, as usual
• Initial support for internationalisation
