AFE4432: AFE4432 fails to capture wrist oximetry PPG waveforms

Part Number: AFE4432

Above is the configuration I made for the AFE4432, no matter I use the SFH7072 light set provided by the AFE4432EVM or our own design(PD:VEMD5010X01
;LED:SFH7015), I can't grab the PPG waveforms of the red and infrared light on the wrist.

What other adjustments do I need to make so that I can grab the red and infrared PPG waveforms on my wrist?
