assembly operand format:
This section describes the operand format used by the assembler when assembling CPU12
instructions. The operand format accepted by the assembler is described separately in the CPU12
Reference Manual. Rather than describe the numeric format accepted for each instruction, some
general rules are used. Exceptions and complicated operand formats are described separately.
In general, anywhere the assembler expects a numeric value in the operand field, either a decimal
or hexadecimal value may be entered. Decimal numbers are entered as signed constants having a
range of -32768 to 65535. A leading minus sign (-) indicates negative numbers, the absence of a
leading minus sign indicates a positive number.
