Hi. I'm trying to find a document that I saw a couple of years ago and foolishly forgot to save. It mentioned bits to be programmed in a register (I believe on the 411) to set up the PCM for 8x, 24x or Northstar signals.
I've traced the CKP input to a chip labeled 11124 (it's a Delco) and of course I can't find a datasheet anywhere for it.
Has anyone seen the document that I am recalling, and know if a copy can be had?
Thanks!

Re: Delco/GM chip documentation
Did you ever find anything about this?

Unfortunately, not yet, though I keep digging...

Re: Delco/GM chip documentation
Unfortunately I cant help with what your looking for but I can like some perhaps interesting info about Delco branded chips.

I'll also attach an EIA PDF which shows General Motors / Hughes Electronics -> Kokomo -> is 466 (source: davelevasseur.com)
You'll see 466 on all the Delco branded chips. Unfortunately there is no public list (that I am aware of) to convert these back to regular part numbers. There are also many "delco 466" datasheets on the internet. Clearly these are all mislabeled

Re: Delco/GM chip documentation
It's definitely a Delco chip...
I am kicking myself for not saving that document. It basically said that the chip is initialized over the SPI and a couple of the bits set it up in 4X, 24X or Northstar mode.
