Question

Please help me solve these problems

Given the command MOV BH,[4567H] and DS = 6440H, show what is on the AD0-AD7 and A8-A19

pins of an 8088 microprocessor during the execution of this command. The contents of memory are

= 42H.

1.At the first clock cycle after command has been transcribed by the processor

2.At the end of the 2ndclock cycle.

3.During the 3rdclock cycle.

4.Draw the timing diagram below

Explanation / Answer

we have command MOV BH,[4567H] so we have form AD0 to AD7 0100,0101,and at A8 to A 15 -->0110,0111 at the first clock cycle and at the next clock cycle ae have 0100,0010 at teh data line,and ine next cycle this data will be moved in Bh
