Hi Everyone,
       I am trying the power down mode in LPC 2138 microcontroller. I
am able to enter in to the power down mode, but not able to get back
if there is an external interrupt. I am using EINT3 to wake up the
controller. Can anybody suggest an idea to go forward?
       Also, Is it possible to configure the LPC 2138 EINT3 to execute
an ISR function, while configured for wakeup?

Advanced Thanks for the suggestions.

Thanks & Regards,
Mohan

Dit you set the EXTWAKE correctly?

what is the power consumption when you power down? did you measure 
it?

I have managed to power down and back quite happily but I was getting 
700 microamps consumption !!

I had it comming alive with both RTC and external interrupts EXTWAKE 
must be set

What did you get for current consumption?

I did have a lot of stuff attached (JTag etc - which I did unplug)  so I 
am builing another board bit by bit and measuing as I go.
