Preface This reference manual describes assembly language programming for Zilog's Z8 single-chip microcomputer. The first three sections of the manual focus on Z8 design features and the assembly-language instruction set. Sections 4 and 5 provide additional information needed to build a source program, including the use of high-level PLZ statements. This manual is one in a series describing the Z8. You will need several other manuals to develop, debug, and run Z8 assembly-language programs. Programs are developed on either Zilog's microcomputer system (MCZ) or the Zilog development system (ZDS) using the software capabilities of the RIO operating system. The manuals needed to use the operating system are: Z80 RIO Operating System User's Manual, 03-0072-01 Z80 RIO Text Editor User's Manual, 03-0074-00 The Z8 assembler produces relocatable object modules. Operation of the assembler and object module linkage and relocation are described in the: Z8 PLZ/ASM Assembler User Guide, 03-3048-02 PLZ Linker User Guide, 03-3098-02 Finally, while this programming manual includes an overview of the Z8 architecture, you will need the following manual for detailed hardware and configuration information: Z8 Microcomputer Technical Manual, 03-3047-02 iii Contents SECTION 1 ARCHITECTURAL OVERVIEW 1.1 Introduction 1-1 1.2 Memory Segments 1-2 1. 2. 1 Program Memory
