Consider the following instructions given in the table below. For each instruction determine changes in registers after its execution. Fill in the empty cells in the table. Initial value of registers R2, R5, and R7 is as follows: R2=0x0007 (Status register), R6 0xAA22, R7-0x21B0. Assume the starting conditions are the same for each instruction in the table (i.e. always start from the initial conditions in registers). Note: Format of the register R2 is shown below.
