Twenty six instructions support absolute addressing.
- ADC (opcode 6D)
- AND (opcode 2D)
- ASL (opcode 0E)
- BIT (opcode 2C)
- CMP (opcode CD)
- CPX (opcode EC)
- CPY (opcode CC)
- DEC (opcode CE)
- EOR (opcode 4D)
- INC (opcode EE)
- LDA (opcode AD)
- LDX (opcode AE)
- LDY (opcode AC)
- LSR (opcode 4E)
- ORA (opcode 0D)
- ROL (opcode 2E)
- ROR (opcode 6E)
- SBC (opcode ED)
- STA (opcode 8D)
- STX (opcode 8E)
- STY (opcode 8C)
- STZ (opcode 9C)
- TRB (opcode 1C)
- TSB (opcode 0C)
- JMP (opcode 4C)
- JSR (opcode 20)
On the SPC700, operands which use absolute addressing are prefixed with an exclamation point (!).
