The operand fields, when present, follow the operation field and are separated from it by a white space. When two or more operand subfields appear within a statement, a comma must separate them.
The following table lists the addressing mode notations allowed in the operand field:
| Addressing Mode | Notation | Example |
|---|---|---|
| Inherent | No operands | RSP |
| Immediate | #<expression> | ADC #$01 |
| Direct | <expression> | ADC byte |
| Extended | <expression> | ADC word |
| Indexed, no offset | ,X | ADC ,X |
| Indexed, 8-bit offset | <expression>,X | ADC Offset,X |
| Indexed, 16-bit offset | <expression>,X | ADC Offset,X |
| Relative | <label> | BRA Label |
| Stack Pointer, 8-bit offset | <expression>,SP | ADC Offset,SP |
| Stack Pointer, 16-bit offset | <expression>,SP | ADC Offset,SP |
| Memory-to-memory immediate-to-direct | #<expression>,<expression> | MOV #$05,MyDataByte |
| Memory-to-memory direct-to-direct | <expression>,<expression> | MOV DatLoc1,DatLoc2 |
| Memory-to-memory indexed-to-direct with post- increment | X+,<expression> | MOV X+,<expression> |
| Memory-to-memory direct-to-indexed with post- increment | <expression>,X+ | MOV <expression>,X+ |
| Indexed with post-increment | X+ | CBEQ X+, Data |
| Indexed, 8-bit offset, with post-increment | #<expression>,X+ | CBEQ #offset,X+,Data |
