Read-Only Author Jon Ward Posted 4-Jan-2001 13:08 Toolset C166	RE: CPU.21 problem - what does it affect? Jon Ward Take a look at the following knowledgebase article. Unfortunately, I couldn't find any information on the Infineon web site about this errata. http://www.keil.com/support/docs/1770.htm Jon
Read-Only Author John Cox Posted 4-Jan-2001 13:17 Toolset C166	RE: CPU.21 problem - what does it affect? John Cox Ummm.. yes - I found that article, and likewise couldn't find anything at Infineon. Unfortunately it doesn't tell me whether the chip I'm targetting (C161U) suffers from this problem, which is why I'm posting here. I'd prefer to avoid stuffing my code with spurious extra atomics.

Andrew Neil You can post questions to Infineon Tech Support via their website: http://www.infineon.com/contact/contact.htm They tend to get a bit shirty if you mail direct to product.support@infineon.com ;-) Or maybe you could try your friendly neighbourhood distributor?
Read-Only Author Keil Support Posted 8-Jan-2001 02:02 Toolset C166	RE: CPU.21 problem - what does it affect? Keil Support Please take a look to the ERRATA sheet that is published on http://www.infineon.com under Products - Microcontroller - C166 Family. Each controller has it's own errata sheet where the CPU.21 problem is mentioned or not.
Read-Only Author John Cox Posted 8-Jan-2001 04:07 Toolset C166	RE: CPU.21 problem - what does it affect? John Cox Thank you for your reply. The C161U has no Errata sheets published on their web site (I can find them for other C16x series chips) - I assume this means that there is nothing wrong with it?
Read-Only Author Andrew Neil Posted 8-Jan-2001 04:25 Toolset C166	RE: CPU.21 problem - what does it affect? Andrew Neil You definitely need to contact Infineon's tech support (see my earlier post) - this can often elicit "missing" documents!
