I am using 68HC11. I need to transfer content of the memory:

  • content of $0098 to $0011
  • content of $0097 to $0010

But there is a limitation so I can not solve this. I have to use at most two instructions for this.

LDD $0097
STD $0010

或者

LDX $0097
STX $0010

或者

LDY $0097
STY $0010

因此,只需使用 16 位指令来进行复制。
