Power down and wake up in LPC

Started by asvi...@yahoo.co.in May 19, 2007
Hi
im working with LPc2106
I need to put LPC in power down mode and wake on external interrupt(EINT0).
Can any one guide me the proper sequence of putting it into power down mode and wake on external interrupt.

I did the following steps but it didnt work

PCON=2 // to put arm in power down mode.
EXTWAKE=1 // to wake up on EINT0
EXTINT0=1 // to clear EXTINT0

Thanks in advance.
regards
asvini

An Engineer's Guide to the LPC2100 Series

Use the example under LCP23xx, the "PWRMan" directory
has something similar you can use.
