The Byte Craft Limited C38 Code Development System supports the entire Mitsubishi MELPS740 (38000) series of microcontrollers, which includes the 7600 series, M509xx, M371xx, M374xx and M38xxx
The C38c Code Development System includes:
• an optimising C
Cross-compiler.
• the BCLink linker.
• an Integrated Development
Environment and editor.
• a built-in macro cross-assembler.
Other features of the C38cCode Development System include:
• Highly optimised generated code. Full versions generate ROMable code, demonstration versions generate listing files with assembly.
• part-specific header files describe the unique features of each target device.
• compiler configuration using #pragma directives.
• ports are declared and protected using the #pragma port series of directives
• the #pragma vector directive specifies the location and assigned name for interrupt sources.
• BClink Linker links object files and libraries compiled with C38.exe
• object libraries can be included directly in C source files using Absolute Code Mode.
• named address spaces support the grouping of variables at specific memory locations.
• SPECIAL address space declares variables at special locations such as external devices or internal EPROM.
• LOCAL address space allows you to use local variables.
• extensions to the C language designed specifically for the embedded systems developer. Some extensions include bit-sized data types, binary constants, extended case statements, direct variable placement with the @ symbol, and support for processor-specific functions.
• interrupt handler support in C; makes context saving and restoring easy.
• data types include:
bit, bits
char, short, int, long
register-oriented types for direct access to processor registers when necessary
• selectable 8 or 16 bit int data type.
• packed bit fields in structs.
• include single and multiple lines of inline assembly within a C program with the #asm and #endasm directives
• extensive control over computer-generated initializations.
• generates source-level information required for emulators. .
• supports processor specific instructions BRK, CLC, CLD, CLI, CLT, CLV, NOP, PHA, PLA, ROL, ROR, RRF, SEC, SED, SEI, SET, STP, WIT
• supports the instruction extensions MUL, 7600
• supports direct access to AC, X, Y and CC registers
