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.
