 		 #13039 - RE: switching a port high/low
Hi Chris,

I'm really shure that this fix the problem. Overwriting /RD and /WR causes always a chrash on using external RAM.

I use mostly 89C51 with internal Flash, so I have overlooked this wrong usage of P3.

In general P3 should only be modified, if you need it really. So also serial communication and interrupt handling can be disturbed.
