1. (a) Write a macro cube that calculates x3 for input single byte signed input value whose address is given as the first parameter and stores the result into a memory whose address is given as the second parameter. Assume the result is 16 bits. (b) write an instruction to call this Macro cube. (c) test this macro in the lab and check if the macro works as expected. (6 pts) Hint: Use S12CPUV2.ReferenceManual.pdf for available instructions for coding.
