Absolute Long Addressing

Absolute Long Addressing is supported by ten instructions:

• ADC (opcode 6F)
• SBC (opcode EF)
• AND (opcode 2F)
• ORA (opcode 0F)
• LDA (opcode AF)
• STA (opcode 8F)
• EOR (opcode 4F)
• CMP (opcode CF)
• JMP / JML (opcode 5C)
• JSR / JSL (opcode 22)

All are four bytes long. This is what the various operand bytes represent:

1. low byte of absolute address (byte within page)
2. high byte of absolute address (page number)
3. bank number

Syntax
