For your first problem range1: FD00 0000 to FDFF FFFF, the answer is 00FF FFFF+1=0100 0000H=1 X 16^6= 1 X (2^4)^6=2^24=2^4 x 2^20. For in binary system 2^10= 1024=1K and 2^20=1K x 1 K = 1M then 2^4 x 2^20=16 M. For the second and the third problem please kindly do the same. … crossroads 46 diner menu WebMar 14, 2024 · An 8085 microprocessor has a 16-bit address bus (A0-A15).
