Hi,

 

I have a question about using ADV212 for JPEG2000 compression under normal host model.

 

On the data sheet, it is said pin of DACK0 must be held high at all times if the DMA interface is not used. Unfortunately, we did not do that, and DACK0 is changeable, sometimes it is high, and other times it is low. Under this configuration, most of the times AVD212 woks very well, but sometimes it dose not work well, and the output will be all 0.

 

Can you tell me, under this configuration, when will ADV212 not work correctly? Thanks!

 

Jiulu
