As table above indicates, exclusive or of 16 bit register D with immediate parameter can be replaced by two 8 bit instructions EORA imm, EORB imm and it will execute faster when 6309 runs in emulation mode. Though one should realize that sequence of 8 bit instructions EORA imm, EORB imm is not exact equivalent of 16 bit EORD imm instruction as condition code CC register is set according result of 8 bit operation in first case and according result of 16 bit operation in second case.
