CROSS ASSEMBLER->Assembler Expressions->Assembler Expressions
Expressions are placed in the operand field and are evaluated by the cross-assembler to give a numerical integer value. An expression may be used anywhere within the operand field where a numerical value is expected. The expression evaluator within the cross-assembler will use 32 bit integer arithmetic to calculate the value of the expression.
The expression may consist of symbols, numbers, literals and operators. Parentheses may be used to define a particular order of precedence. Parentheses can be nested.
The following operators are allowed:
Addition | + | |
Subtraction | - | |
Multiplication | * | (or !*) |
Division | / | (or !/) |
Exponentiation | !^ | |
Logical AND | !. | |
Logical OR | !+ | |
Logical exclusive-OR | !X | |
Shift right | !> | |
Shift left | !< | |
Rotate right | !R | |
Rotate left | !L |
