Tool/software:
Since this device is under an NDA, I am not going to into the details of the issue. To summarize, I am having trouble setting the DRE-specific registers to get a clean PPG signal with small DC part. Unfortunately, I wasn't able to understand from the datasheet, what kind of effect do the DRE registers have on the PPG signal. Moreover, I want to utilize all 4 LED drivers, but that would require more PPG phases than what the device support. Can you maybe clarify if I am setting the registers incorrectly?
