Assembly and Object Code

Example

Table 27 provides an example listing file output for an assembled 

eZ8 CPU program. Most of the Op Codes appear in this list. The table is

sorted alphabetically by the instruction mnemonics. Each instruction line

consists of the Program Counter address for the instruction, the object

code, and the assembly code (instruction and operands). The

ORG %1000

assembly code is an assembler directive which sets the base Program

Counter value. The labels (LABEL1:, LABEL2:, and LABEL3) are also

assembly directives used to indicate addresses.
