Write an Assembly Language Program to exchange the nibbles of 8-bit number stored in memory location 4500H. Store the result at memory location 4501H.
|LXI, 4500 H||; Set H-L pointe r to 4500 H|
|MOV A, M||; take no. in accumulator|
|RRC||; with 4 RRC instructions|
|RRC||; Interchange the digits of the no.|
|INX H||; Increment HL pair by 1|
|MOV M, A||; store the exchanged no. in 4501 H|
|RST 1.0||; Restart|
