#12719 - RE: Checking the address and data lines |
Just write a small prog.
a) for 89c51 . write ffh then delay of one sec and then 00h on all the ports. b) Use for movx command in any sample program for checking address data line. While doing this connect a loop wire to ALE and keep a radio besides and tune for the 1/6th of the xtal freq. regards jayan |
