5.5 ASSEMBLER OPTIONS
The CASM05W assembler supports all Motorola opcode mnemonics in the command set. For
descriptions of the debugging commands, see Chapter 7, ICS05KJW Debugging Command Set.
5.5.1 Operands and Constants
Operands are addresses, labels, or constants, as defined by the opcode. Assembly-time arithmetic
is allowed within operands. Such arithmetic may use these operations:
Operator precedence follows algebraic rules. You may use parentheses to alter precedence. If
your expression contains more than one operator, parenthesis, or embedded space, you must put
the entire expression inside braces ( { } ).
Constants are specific numbers in assembly-language commands. The default base for constants
is hexadecimal, but you may change the default using the Change Base Address dialogs for the
Memory and Code windows. To temporarily override the default base, use either the appropriate
prefix or suffix (Table 5-1), but not both.
The assembler also accepts ASCII constants. Specify an ASCII constant by enclosing it in single
or double quotes. A character ASCII constant has an equivalent value: ‘A’ is the same as 41H.
An example of a string constant is:

Opcodes mnemonics cannot start in column one. If a label begins
the line, there must be at least one space between the label and the
opcode.
