Answer 1

Answer 2

Question 1 answer is 0,1,2,3,4,5,6 and 7

following I what bit positions to of in R4 will be inverted when the INV operation is executed Invob R4 From the given R4 is 8 bit Register & R4 is invested then all bit positions are inuested So the answer is 0,1,2,3,4,5,6,7 2 R4 is a sbit register When AND operation is executed the register value ouillio from this 7th & oth bit position is cleared to "o' so R4 will be cleared o and 7 bit positions 3. R4 is a a obit register orb #ollllllob , R4 when or operation is executed the register value 01111110' From this 1, 2, 3, 4, 5,6 bit positions set to I so R4 will be set the 1,2,3,4,5,6 bit peritone

Question 2 answer is 0 and 7

Question 3 answer is 1,2,3,4,5 and 6
