I have read the data sheet. if PxM0.y=0 and PxM1.y=0 then it will work as standard 8051MCU. but i want to know how can i make PxM0. abu.saeed.mirza@nospam.com (Mirza123) http://www.8051projects.net/plugins/forum/forum_viewtopic.php?65855 Re: AT89LP2052 connection See section 15 (Ports) of the data sheet.
