RA78K0R, CC78K0R

Development tools (assembler, C compiler) for 16-bit 78K0R Microcontroller can be downloaded from here.


RA78K0R

RA78K0R is a generic name for a series of programs used to translate source programs for the 78K0R Microcontrollers written in assembler language into machine language.
The RA78K0R includes the following programs.



Restrictions

  • The useable memory area is limited to 64KB (0-FFFFh) in the internal ROM and the internal RAM.
    Also, the memory area that can be redefined by a directive is the same.
    Because of this limitation, the MAA of the Processor mode control register (PMC) has to be set to "0" and the mirror area selections in the compiler options and the linker options have to be "-mi0".

Functions and features

  • Outputs diagnostic information
    • The RA78K0R outputs a range of diagnostic lists (assemble list, symbol list, cross-reference list, error list, etc.) to aid debugging work.
  • Macro function
    • The RA78K0R supports a macro function by which similar instructions are grouped as a single macro instruction. This function can be used to reduce the amount of coding, leading to higher quality program development.
  • Conditional assemble function
    • The RA78K0R supports a conditional assemble function by which the user can set whether to assemble part of the source program according to certain conditions. This function allows source programs that partially differ according to the machine type to be managed uniformly, which leads to improved maintainability.
  • Branch instruction optimization function
    • The RA78K0R includes a quasi directive that automatically selects the RA78K0R branch instruction (BR quasi directive). This directive enables the assembler to generate the appropriate branch instruction code for the branch instruction destination range.

PM+

The PM+ project manager is an integrated development environment platform that integratesRenesas Electronics development tools (as well as some third-party tools) on Windows so as to improve their operability. PM+ is included in the assembler package.
Operations in user program development such as starting the editor, builder, and debugger can be executed serially from PM+.


Functions and features

  • Multiple project management
    • Multiple project files can be managed on PM+ as a single group by employing concepts such as workspaces and project groups.
  • Builder startup
    • Tools required for creating an application system (C compiler, structured assembler preprocessor, assembler, linker, object converter, etc.) can be started up from PM+.
  • Editor startup
  • Debugger startup
  • External tool registration, execution
  • Links with source management tools
  • Matching of specifications and comments
    • PM+ supports a function for effectively adjusting specifications in the specification study phase (idea processor function) and reflecting those adjustments as comments in the source program.

CC78K0R

The CC78K0R is a versatile, portable C compiler developed for describing the embedded control programs of 78K0R single-chip microcontrollers in C language. Using this compiler enables a much shorter development lead time and a reduction in the number of development man-hours.
In addition to the standard C language specifications, the CC78K0R also supports extended specifications peculiar to the 78K0R Microcontrollers. This not only broadens the usefulness of the C compiler, but also allows for a considerable expansion in C language applicability.
Note:
When you would like to use CC78K0R, please use RA78K0R simultaneously.
Because CC78K0R has no workbench (PM+), linker and object converter.


Functions and features

  • ANSI-C compliant
    • The CC78K0R is compliant with the standard C language specification, ANSI-C.
      ANSI : American National Standards Instltute
  • Supports extended specifications peculiar to 78K0R Microcontrollers
    • The CC78K0R provides extended specifications for easily describing control and interrupt servicing programs for the peripheral hardware incorporated in the 78K0R Microcontrollers in C language. Extended specifications for improving the ROM/RAM efficiency are also provided.
  • Emphasizes ROM/RAM efficiency
    • Powerful optimization enables the output of compact code.
    • External variables can be assigned to the saddr area (Note) (sreg variable). Function arguments and automatic variables can also be assigned to the saddr area or registers (norec, noauto functions).
      The code size can therefore be reduced and the execution speed improved.
      Note:An area allocated to the internal RAM of the 78K0R Microcontroller, accessible using instructions with a small byte count. A wide range of transfer and operation instructions are provided, making operability particularly good.
    • One-bit data can be defined and manipulated using the bit manipulation instructions of the 78K0R Microcontrollers.
    • Functions that can be called using short instructions can be described (callt, callf functions).
  • Awareness of embedded control
    • The peripheral hardware of the 78K0R Microcontrollers can be controlled directly in C language.
    • Interrupt servicing can be described directly in C language (register banks are switchable).
    • Special instructions such as interrupt disable/enable and rotate can be output using embedded functions.
    • Assembler descriptions can be made in the C source.
  • Supports libraries effective for embedded applications
    • From among the standard library functions defined by the ANSI-C specification, the CC78K0R provides standard support for libraries that are effective for embedded applications.
      Library source programs are also available for reference (sold separately).
  • Function information output
    • The CC78K0R outputs statically calculated information such as the size and number of stacks in defined functions to the assembler source module file.
