 For arithmetic instructions, the lower 2 bits of <sop> encode addressing mode:
 
-       0?: arg_a = previous value of accumulator, arg_b = mem[x]
-       1?: arg_a = mem[y], arg_b = mem[x]
+       0?: arg_a = mem[y], arg_b = mem[x]
+       1?: arg_a = previous value of accumulator, arg_b = mem[x]

        ?1: store result to both accumulator and mem[y]
