I'm trying to read an encoder with 32 bits of count info. Look at

http://files.pepperl-fuchs.com/selector_files/navi/productInfo/edb/t168…

It would appear to have a total of 32 bits of count info an a "special bit" .The command reference for the DMC4080 says the the max number of bits, I think including any extra bits is 31. Application Note # 2438 makes no mention and seems to imply that the number of bits "n" is one less then the total number of bits. Application Note # 2438 also makes no mention of the max number of bits.

I also found it interesting that Application Note # 2438 mentions that negative values for p change the edge that data is clocked in on. I don't think that this is mentioned in the command reference.

Any help would be great!
