 		 #55045 - trouble of using P89c51rb2

I'm using P89C51Rx2 in my design.
But I hope my circuit can use other 805x mcu without ISP, too.
I found my program can't execute after I write program code into P89c51rb2 by ISP function.
I check and find that P89c51rb2 is in ISP mode each power-on, but I am sure PSEN pin is open.
How can I do to let mcu run my program ?
