I am solving Micro Corruption CTF (msp430 assembly)

How can I put the value 0x3c4f inside address 0x439c (r15 from Register state)? When cmp instruction executes, we want the value at memory address 0x439c to be equal to 0x3c4f.

enter image description here

One thing to note is cmp instruction will compare 2 bytes

.W : The suffix .W or no suffix at the instruction memonic will result in a word operation

I appreciate your help!

Should I put 3 in 0x439c, c in 0x439d, 4 in 0x439e and f in 0x439f?
