12. Computers recognize Base 16 (hex) Binary Hex 0000 0 0001 1 0010 2 0011 3 0100 4 0101 5 0110 6 0111 7 1000 8 1001 9 1010 A 1011 B 1100 C 1101 D 1110 E 1111 F

18. Features Of 89c51 IC • FLASH EPROM internal program memory with Chip Erase. • Up to 64 k byte external program memory if the internal program memory is disabled (EA = 0). • Programmable security bits. • 100 minimum erase/program cycles for each byte. • 10 year minimum data retention. • Programming support available from many popular vendors.

20. (DIP switches) Dual Interface Poll switches usually allow you to change the configuration of a circuit board to suit your application.

22. Since its base is 16= 24, every 4 bit binary digit combination can be represented by one hexadecimal digit. Each significant position in an hexadecimal number has a positional weight.

23. These weights are given in the ascending powers of 16. i.e., 160, 161, 162, …. etc

25. Now from fig. there is one DIP swich put in curcuit.

26. In one DIP swich Four Port Are Available Who having a power supply.

27. Now first of all allswich is off Position That’s why HEX value is zero.

28. Now Only one Swich is at ‘1’ or ‘ON’ position & other is ‘off’. Hence, we get HEX value as ‘1. Due to 89c51 IC’s inbilt process.

29. So, Like vise if on All the SwichesSo we can get ‘F’.. HEX value..
