2. (sim. To Jimenez 4.2). In the MSP430 machine language, an instruction word with two operands is decoded in four nibbles, where the most significant nibble is the opcode. For the Register addressing mode, the least significant nibble is the number for the destination register and the nibble next to the opcode is the source register. Consider the assembly and hex machine versions for the executable code in Jimenez Fig. 4.5 and answer the following questions: a. How many two-operand instructions are there in the example code? b. For each two-operand instruction, associate the mnemonic with the corresponding opcode. c. In the format Rn, what value of n corresponds to register SR (Status Register)? d. Does des.w. R15 have a source register? If affirmative, tell which one is it and why is it there. If negative, justify your answer e. What is the machine instruction word for mox.x. WOxC350, R10 and des R157 2.
