1. Suppose the Pep/9 system contains the following four hexadecimal values: register A: register X: Mem[091D]: Mem[0A71]: 25B6 AE20 OFFO 301D If these are the values before each of the following instructions executes, indicate which of these values is changed when each statement is executed, and show the new value. If a register or a memory location shown above is unchanged by the instruction, don't show its contents; only show the item that changed and what the new 16-bit value of that item would be. Note: reset the contents of the registers and memory locations to the given values above before executing each of the following instructions (in other words, these instructions are independent of each other).

1. Suppose the Pep/9 system contains the following four hexadecimal values:
register A:
register X:
(c)
Mem[091D]:
Mem[0A71]:
If these are the values before each of the following instructions executes, indicate which of these values is
changed when each statement is executed, and show the new value. If a register or a memory location
shown above is unchanged by the instruction, don't show its contents; only show the item that changed and
what the new 16-bit value of that item would be. Note: reset the contents of the registers and memory
locations to the given values above before executing each of the following instructions (in other words,
