8051 code to use R4(LSB) and R5(MSB) as a single 16bit counter, and increment the pair untill number is FFFFh
Logic is too simple. For better understanding, I would suggest you something. Use a scientific calculator and in hex mode go on adding 0x01 each time. And then study my code. You will have a better understanding. ORG 000h MOV R4,#00h MOV R5,#00h main: INC R4…
8051 code to use R4 (LSB) and R5(MSB) as a single 16-bit counter and decrement the pair until number is 0000h
The logic is easy. Go on decrementing LSB . Let me consider an example. let the number be 0xffff . this means 0xff in both R4 and R5 registers. go on decrementing R4(LSB).once it reaches 0x00,then decrement R5(MSB) which makes it 0xfe in R5. Then reset the value of R4…
