Stack Relative Addressing is supported by eight instructions:
- ADC (opcode 63)
- AND (opcode 23)
- CMP (opcode C3)
- EOR (opcode 43)
- LDA (opcode A3)
- ORA (opcode 03)
- SBC (opcode E3)
- STA (opcode 83)
The effective addresses generated by stack relative addressing will always be in bank 0.[3]
Syntax
