The memory of a computer (some addresses only) contains the following. Addresses and contents are in hexadecimal. 006 0007 007 1006 008 5006 009 0000 LIST OF OPCODES (OPCODE is in binary) 0000 = HAT; halts execution of an instruction cycle; does not update !! registers 0001 = Load AC from memory 0010 = Store AC to memory (where to?) 0101 = Add to AC from memory The current instruction has just completed its execution. PC holds the hexadecimal value 007. AC holds the hexadecimal value 0077. The microprocessor continues its program execution with the next instruction. Answer the following questions. (1) When the microprocessor completes its program execution what are the contents of register PC in hexadecimal? (answers in 0X) OX010 (2) When the microprocessor completes its program execution what are the contents of register AC in hexadecimal? (answers in 0X) OX0007
