See the Labels section on page 332 and the Hexadecimal Numbers section on page 291 for
more information.
Instruction
An instruction contains one valid assembler instruction that consists of a mnemonic and its
arguments. When an instruction is in the first column, it is treated as an instruction and not
a label. Use commas to separate the operands. Use a semicolon or carriage return to termi-
nate the instruction. For more information about Z8 Encore! CPU instructions, see the eZ8
CPU Instruction Set Description section of the
eZ8 CPU User Manual (UM0128) .
Directive
A directive tells the assembler to perform a specified task. Use a semicolon or carriage
return to terminate the directive. Use spaces or tabs to separate the directive from its oper-
ands. See the
Directives section on page 294 for more information.
Case Sensitivity
In the default mode, the assembler treats all symbols as case-sensitive. Select the Ignore
Case of Symbols checkbox of the General page in the Project Settings dialog box to
invoke the assembler and ignore the case of user-defined identifiers (see the Ignore Case
of Symbols section on page 71). Assembler reserved words are not case-sensitive.
Assembler Rules
The following sections describe the assembler rules:
•
Reserved Words – see page 285
•
Assembler Numeric Representation – see page 287
•
Character Strings – see page 287
Reserved Words
The following list contains reserved words that the assembler uses. You cannot use these
words as symbol names or variable names. Also, reserved words are not case-sensitive.
