Question

Read the error message and correct the error parts in the code 1-1. This assembly code loads the hex values to the general purpose registers, R16 and R17. Then, it swaps the contents of the registers. Answer the questions. ; load a value to a general purpose register ldi r16,3256 lds r17,5412 mov r22,r16 mov r16,r17 mov r17,r22 swap the values of the register 16 and 17 Q. What is the syntax error in this code? Q. How to fix the error? Show your modified code and the registers' values after perform the code.

Explanation / Answer

A) the seconds line using lds r17,542, will give the syntax error as lds is used to load directly from the space but here the data provided is immediate so ldi is used instead of lds.

B) modified code :

ldi r16,3256

ldi r17, 5412

mov r22, r16

mov r16, r17

mov r17, r22

Register values are : r16 = 5412

r17 = 3256

r22= 3256
