the binary value of second digit of the hexadecimal number indicates that status‚ “1” for “off” while “0” for “on”; For example‚ “e” in binary is 1110‚ coil A is turned on (controlling coil A to D from the most right bit to most left). So to turn on coil C only‚ a binary number 1011 (in hexadecimal “b”) is needed and the code for it is shown as follows: cbDout(BOARD_NUM_0‚FIRSTPORTA‚0xfb) Similarly to turn on coil C and D‚ a binary number 0011(in hexadecimal “3”) is needed and the code for it is

CONCLUSION. Assembly language is a representation of machine language. In other words‚ each assembly language instruction translates to a machine language instruction. The advantage of assembly language is that its instructions are readable. For example‚ assembly language statements like MOV and ADD are more recognizable than sequences of 0s and 1s. Though assembly language statements are readable‚ the statements are still low-level. Another disadvantage of assembly language is that it is not portable

if each cell’s address can be represented by two hexadecimal digits? What if four hexadecimal digits are used? Explain your answer. Answer: Hexadecimal digits is a base 16 number system and it ranges between 0 and F i.e. 0 - 9 and A - F (10 -15). (Table 1 below shows binary‚ decimal and hexadecimal representation). Two hexadecimal digits will be between 00 and FF and this will make up to 256 cells i.e. 0 – 255 (16 bits) and for four hexadecimal digits will be between 0000 – FFFF and this makes
