Suppose the memory cells at addresses 00 through 05 in the machine described in Appendix C contain the following bit patterns: $$\begin{array}{cc} \text { Address } & \text { Contents } \\ 00 & 22 \\ 01 & 11 \\ 02 & 32 \\ 03 & 02 \\ 04 & \mathrm{C} 0 \\ 05 & 00 \end{array}$$ Assuming that the program counter initially contained $00,$ record the contents of the program counter, instruction register, and memory cell at address 02 at the end of each fetch phase of the machine cycle until the machine halts.
The range of the values -5, -8, -10, 0, 6, 10 is 0 Select one: True False

Suppose the memory cells at addresses 00 through 05 in the machine described in Appendix C contain the following (hexadecimal bit patterns: $$\begin{aligned} &\begin{array}{cc} \text { Address } & \text { Contents } \\ 00 & 25 \\ 01 & \text { B0 } \\ 02 & 35 \\ 03 & 04 \\ 04 & \text { C0 } \\ 05 & 00 \end{array}\\ \end{aligned}$$ If we start the machine with its program counter containing $00,$ when does the machine halt?
