    My project is of security system.

    I'm interfacing a keypad,if pw is wrong then it'll blow siren and if right then it'll ON LED and goes to Power Saving Mode..
    This is actually a small part of my project..

    i want to know that can i keep LED ON even in sleep/Ideal mode...
    I also want to know activation process of Ideal mode and can i wake it up from sleep (actually not want to reset ,it rune my data).

    and yes i forget to mention i'm using 89c51 mc.
    thank you friends...:)
