Power down mode & wakeup

2004-07-06 by nedeljkomiljevic

Hi all,

has anybody tried to put the LPC in power down mode?
What would be the proper sequence of putting it into power down mode
and wake on external interrupt?
I have done the following:

(will use EINT2 for wakeup, the program starts with EINT2 mapped to IRQ)

............

power down:

- disable EINT2 interrupt
- EXTWAKE = 4
- PCON = 2
(here the processor stops)

but on triggering EINT2 the processor does not continue running,
have to reset the controller instead (undesirable).

Any ideas/hints? 

Thank you

Nedeljko
