Can anyone plz upload the timing diagram for instruction

ADD AX, TAX

when TAX begins at an odd address in 8086 µp :?:
 

8086 µp instruction - help me

first read from address tax in 4 clock ( BHE=0 , a0=1) then read from tax+1 ia 4 clock time with BHE=1 and a0=0
 

8086 µp instruction -25 points

Hi;
ADD - Arithmetic Addition

Usage: ADD dest,src
Modifies flags: AF CF OF PF SF ZF

Adds "src" to "dest" and replacing the original contents of "dest".
Both operands are binary.

Clocks Size
Operands 808x 286 386 486 Bytes

reg,reg 3 2 2 1 2
mem,reg 16+EA 7 7 3 2-4 (W88=24+EA)
reg,mem 9+EA 7 6 2 2-4 (W88=13+EA)
reg,immed 4 3 2 1 3-4
mem,immed 17+EA 7 7 3 3-6 (W88=23+EA)
