In released Compaq spec on page 2 "Aditional feutures built into SA-1110 chipset" it says something about "Four general purpose interruptible timers" sounds interesting, i did not found any information about those can be used ? Or is it in the SA1110 Developers Manual, something integrated in the SA1110 that is something that i don't have any knowledge about. But I will check that now. However there's a external timer controller that are running the SA1110 will only wakup on programed interrupt source set in the PWER register and it's only set to GPIO1 that is the Power button on the iPAQ. So it will not wakeup however a timer is running. But if it's true that there is a timer running during sleep it should be turned off to save power. /Benny _______________________________________________ http://lists.arm.linux.org.uk/mailman/listinfo/linux-arm Please visit the above address for information on this list.
