There are three types of Implied Addressing on the 65c816:
Type 1 - The register(s) to be operated on are implied in the mnemonic: (17 instructions)
- DEX (opcode CA)
- DEY (opcode 88)
- INX (opcode E8)
- INY (opcode C8)
- TAX (opcode AA)
- TAY (opcode A8)
- TCD (opcode 5B)
- TSC
- TDC (opcode 7B)
- TSC
- TSX
- TXA
- TXS
- TXY (opcode 9B)
- TYA
- TYX
- XBA (opcode EB)
Type 2 - The flag(s) to be operated on are implied in the mnemonic: (8 instructions)
Type 3 - Neither flags nor registers operated on: (4 instructions)
All implied instructions except for WDM are one byte long.
