The Byte Craft Ltd Z8C Code Development System is supports the Zilog Z8 family of microcontrollers.

Operating System Support

• DOS

The Z8 C Code Development System includes:

• an optimizing Z8 C Compiler.
• the BCLink linker.
• an Integrated Development Environment and editor.
• a built-in Z80 macro cross-assembler.

C Compiler Features In Detail

• part-specific header files describe the unique features of each Z8 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 withZ8 C-compiler z8c.exe
• Z8 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 the bit and bits 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
• 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 initialization.
• generates source-level information required for Z8 emulators.
• supports the Z8 instruction extensions C94, C95, HALT, MUL, STOP, WAIT
• supports Z8 microcontroller specific instructions DI, EI, HALT, NOP, RCF, SCF, STOP, WAIT, WDT, WDH
• supports direct access to IPR, IMR, IRG, FLAGS, RP, SPH, SPL registers
