TLK100 ALCD

Other Parts Discussed in Thread: TLK100

I am trying to run ALCD test and for some rason i get ony the result 0x0003 in CDRR.

I have "copied" the example code from the site even though i didnt understode eveything, for example: what is the "pre test"? how long it should be? how did Aval and Bval ceoffitiants calculated?

another thing is that the "alcd/sda done" bit is '1' and the 'tdr done' is '1' from reaset, why? in what cndition thus bits are cleared?

I also saw some other strange things in the example code, like the B8 and B4 registers, what are they?

 

basicly i think that alot of decomentation about this part is missing, any help, examples codes will be appreciated
