AFE4900: Data converters forum

Part Number: AFE4900

Hello. I want to test the ECG DC Lead-off Detect function of AFE4900.

I set EN_ILEADOFF and  EN _LEADOFF_COMP to 1,and set the PROG_VCOMP_HIGH、PROG_VCOMP_LOW、POL_ILEADOFFP、POL_ILEADOFFM and MAG_ILEADOFF  as well.The register value are 0x128004(4Eh),0xE00000(62h). But the value I read from 63h is always 5.

I want to know how to tell if the electrodes is fall off.

Thanks.

Best regards.
