There are several types of Stack Addressing:
Absolute:
- PEA (opcode F4)
Direct Page Indirect:
- PEI (opcode D4)
Interrupt:
Program Counter Relative Long:
- PER (opcode 62)
Pull:
Push:
- PHA (opcode 48)
- PHB (opcode 8B)
- PHD (opcode 0B)
- PHK (opcode 4B)
- PHP (opcode 08)
- PHX (opcode DA)
- PHY (opcode 5A)
RTI:
RTL:
- RTL (opcode 6B)
RTS:
Relative:
- ADC (opcode 63)
- AND (opcode 23)
- CMP (opcode C3)
- EOR (opcode 43)
- LDA (opcode A3)
- ORA (opcode 03)
- SBC (opcode E3)
- STA (opcode 83)
Relative Indirect Indexed, Y
- ADC (opcode 73)
- AND (opcode 33)
- CMP (opcode D3)
- EOR (opcode 53)
- LDA (opcode B3)
- ORA (opcode 13)
- SBC (opcode F3)
- STA (opcode 93)
The effective addresses generated by stack addressing will always be in bank 0.[3]
