avr单片机大多数指令都是16位的,而存储器是8位宽的,所以一条指令应该占用2个存储器地址啊
为什么这个题说一条16位的指令占用1个存储器地址呢?
Show the value of the instruction location counter (ILC) after every line of the program
(“nested.asm”) on the next page. You may assume all instructions are 16‐bit instructions
(ie they each occupy one program memory location). Which instructions require the
second pass through of the program, to become completely resolved? |
