I have a question about the TFS signal of an SPORT in an ADSP 21061: I set up the TFS of SPORT 1 as follows: Internally generated (ITFS = 1), data independent (DITFS = 1), late (LAFS = 1), active low (LTFS=1). When SPORT is enabled it works as expected

Hello! We're using SPORT in multichannel autobuffer mode, SCLK and TFS/RFS are generated externally. After some special signal becomes high (let's call it RESET) SCLK/TFS/RFS are masked and SPORT should be disabled by DSP. When RESET becomes low SPORT needs to be reenabled. But after reenabling SPORT we have some corrupted data at DT. And (as we suppose) because RESET is async with DSP ...

I have an instance where I intermittently lose sport data. I am using an AKM codec that interleaves two channels into sport 0 on the 21065L. This works perfectly. I get 16 sets of bits, each coming in and giving me an interrupt every 142us. Runs for hours. Then, for some odd reason, the interrupt waits for 151us, which is after a 17th set of bits came through. When I look at the data then, I ...

Hi friends ADSP 2181 and BF533 are not compatible. ADSP2181 is a 5V logic(TTL) while BF533 is a 3.3V logic device. If i need to connect ADSP2181 sport to BF533 sport is it enough if i use a voltage divider for level shifting? If not which level shifter IC is ideal in this case? I need to level shift all 5 signals on ADSP2181 sport i.e DT,DR,TFS,RFS,SCK.
