Hi,
There are new SA mode in my files at 3chip group, for SA2 and SA3
Rev7t1d2 is not working, for SA2 there is a flag from lines 17/19
but for SA3 I don't see any flag for invert decision.
The DC shift from lines 17/19 can be used to check the invert decision,
may be a sample & hold and a LM339 for this job.
Any Idea/suggestions???
