It's a battery backed crystal based clock, generally. BruceEwing 10:38, 19 November 2006 (UTC)
Is there any reason that we're mentioning a specific Philips microcontroller on this page? I found a hastily written statement, which I edited and linked to the product page, but it seems somewhat overly-specific and out of place. --ThinkingInBinary 14:11, 6 March 2007 (UTC)
- I have no idea, someone sorta left it there. I'm going to remove it. Codeczero 02:41, 24 August 2007 (UTC)
I think the fact that it associated with IRQ 8 should be mentioned. CPU MeltDown 14:09, 29 May 2007 (UTC)
the page now has several references, they aren't great, im not super fond of using application notes (although i did use 3 different manufacturers). if you can find better references feel free to replace mine Codeczero 02:30, 24 August 2007 (UTC)
How exactly does it work?
I have a strong impression that it is battery powered, but how exactly does it still precisely retain the right time when my system is off? By off I mean unplugged, computer packed in a box while moving to a new residence. Same thing with gameboys and other devices. I haven't really tried to remove the batteries for a couple months to see if the gameboy will still preserve the correct time, but I had my gameboy on the shelf untouched for 3 years with the same batteries, and it's fine. There must be some mechanical aspect in the technology that keeps it going.
