## Question:

Repeat Problem 8-22 for the two instructions: Add and check OV (AOV), described by the register transfer

and branch on overlow (BRV), described by the register transfer

The opcode for AOV is 1000101 and for BRV is 1000110. Note that register R8 is used as a “status” register that stores the overlow result V for the previous operation. All of the values N, Z, C and V could be stored in R8 to give a complete status on the prior arithmetic or logic operation.
