(b) Change the first line of the program so that BNE DLY is executed 34 times (c) Change the second line of the program so that BNE DLY is executed 34 times, while the fist line stays unchanged (MOV CX, 1100H)The numbers from 0-9 and a no characters is the Basic 1 digit seven segment display * .can show False True In a (CA) method of 7 segments, the anodes of all the LED segments are * "connected to the logic "O False True Some times may run out of pins on your Arduino board and need to not extend it * .with shift registers True False- The stack memory is addressed by a combination of the plus offset. The PUSH and POP instructions always transfer between segment -bit number the stack and a register or memory location in the 8086 microprocessors. For string instructions, DI always addresses data in the segment. The 8086 LOOP instruction decrements register for a 0 to decide if a jump occurs and tests it
