Thanks for your help,..


Given the command MOV [BX],DH and DS=4000H, BX=1234H, DX=4030H, show what is on the

AD0-AD7 and A8-A19 pins of an 8088 microprocessor during execution of this command.


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
