Hi!
I'm checkin on another base of data. I've downloaded 244 datasheets, 66 of
which contain more than 1* occurrence of "LFSR". All of those explain one of
two possible bitfield patterns, which are the patterns for 12 and 14 bit we
discussed.
Manually reading the results, I can confirm that only these families do have 14
bit:
*k42*k83*q40*q41*q43*q84
That is, if I did catch all of the relevant data sheets.
Greets,Kiste
* 1 occurrence is used as abbreviation for "Linear Feedback Shift Register"
