Stack Addressing

There are several types of Stack Addressing:

Absolute:

• PEA (opcode F4)

Direct Page Indirect:

• PEI (opcode D4)

Interrupt:

• BRK (opcode 00)
• COP (opcode 02)

Program Counter Relative Long:

• PER (opcode 62)

Pull:

• PLA (opcode 68)
• PLB (opcode AB)
• PLD (opcode 2B)
• PLP (opcode 28)
• PLX (opcode FA)
• PLY (opcode 7A)

Push:

• PHA (opcode 48)
• PHB (opcode 8B)
• PHD (opcode 0B)
• PHK (opcode 4B)
• PHP (opcode 08)
• PHX (opcode DA)
• PHY (opcode 5A)

RTI:

• RTI (opcode 40)
• RETI

RTL:

• RTL (opcode 6B)

RTS:

• RTS (opcode 60)
• RET

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]
