eZ8 CPU Instruction Set
Assembly Language Programming Introduction
PS024314-0308
The eZ8 CPU assembly language provides a means for writing an application program
without concern for actual memory addresses or machine instruction formats. A program
written in assembly language is called a source program. Assembly language allows the
use of symbolic addresses to identify memory locations. It also allows mnemonic codes
(opcodes and operands) to represent the instructions themselves. The opcodes identify the
instruction while the operands represent memory locations, registers, or immediate data
values.
Each assembly language program consists of a series of symbolic commands called
statements. Each statement can contain labels, operations, operands, and comments.
Labels are assigned to a particular instruction step in a source program. The label
identifies that step in the program as an entry point for use by other instructions.
The assembly language also includes assembler directives that supplement the machine
instruction. The assembler directives, or pseudo-ops, are not translated into a machine
instruction. Rather, the pseudo-ops are interpreted as directives that control or assist the
assembly process.
The source program is processed (assembled) by the assembler to obtain a machine
language program called the object code. The object code is executed by the eZ8 CPU. An
example segment of an assembly language program is detailed in the following example.
