I am working with these 2 ICs, and I have already configured registers for get working in 12 leads configuration measurement. You can see this in the previous post. However the signal recollected in the second chip is not the expected.

 

As you can see, signals coming from ADAS1000-4 (L1, L2, L3, AVR, AVL, AVF and V2) are correct, but signals coming from ADAS1000-2 (V3, V4, V5, V6 with exception of V1) are wrong. 

 

In ADAS1000-2 I have configured this registers:

reg = ADAS1000.REG_CMREFCTL
val = ADAS1000.MASK_CMREFCTL_LARLD | \
      ADAS1000.MASK_CMREFCTL_LLRLD | \
      ADAS1000.MASK_CMREFCTL_RARLD | \
      ADAS1000.MASK_CMREFCTL_V1RLD | \
      ADAS1000.MASK_CMREFCTL_V2RLD | \
      ADAS1000.MASK_CMREFCTL_CEREFEN | \
      ADAS1000.MASK_CMREFCTL_EXTCM

reg = ADAS1000.REG_FRMCTL
val = ADAS1000.MASK_FRMCTL_RESPPHDIS | \
      ADAS1000.MASK_FRMCTL_GPIODIS | \
      ADAS1000.MASK_FRMCTL_CRCDIS | \
      ADAS1000.MASK_FRMCTL_DATAFMT | \
      ADAS1000.MASK_FRMCTL_SKIP_4TH

reg = ADAS1000.REG_ECGCTL
val = ADAS1000.MASK_ECGCTL_LAEN | \
      ADAS1000.MASK_ECGCTL_LLEN | \
      ADAS1000.MASK_ECGCTL_RAEN | \
      ADAS1000.MASK_ECGCTL_V1EN |  \
      ADAS1000.MASK_ECGCTL_V2EN | \
      ADAS1000.MASK_ECGCTL_GAIN_2_8 | \
      ADAS1000.MASK_ECGCTL_VREFBUF | \
      ADAS1000.MASK_ECGCTL_CLKEXT | \
      ADAS1000.MASK_ECGCTL_GANG | \
      ADAS1000.MASK_ECGCTL_HP



In ADAS1000-4 I have configured this registers

reg = ADAS1000.REG_CMREFCTL
val = ADAS1000.MASK_CMREFCTL_LARLD | \
      ADAS1000.MASK_CMREFCTL_LLRLD | \
      ADAS1000.MASK_CMREFCTL_RARLD | \
      ADAS1000.MASK_CMREFCTL_CERLD | \
      ADAS1000.MASK_CMREFCTL_CEREFEN | \
      ADAS1000.MASK_CMREFCTL_DRVCM | \
      ADAS1000.MASK_CMREFCTL_RLD_EN | \
      ADAS1000.MASK_CMREFCTL_SHLDEN

reg = ADAS1000.REG_FRMCTL
val = ADAS1000.MASK_FRMCTL_V1DIS | \
      ADAS1000.MASK_FRMCTL_V2DIS | \
      ADAS1000.MASK_FRMCTL_RESPPHDIS | \
      ADAS1000.MASK_FRMCTL_GPIODIS | \
      ADAS1000.MASK_FRMCTL_CRCDIS | \
      ADAS1000.MASK_FRMCTL_DATAFMT | \
      ADAS1000.MASK_FRMCTL_SKIP_4TH

reg = ADAS1000.REG_ECGCTL
val = ADAS1000.MASK_ECGCTL_LAEN | \
      ADAS1000.MASK_ECGCTL_LLEN | \
      ADAS1000.MASK_ECGCTL_RAEN | \
      ADAS1000.MASK_ECGCTL_GAIN_2_8 | \
      ADAS1000.MASK_ECGCTL_VREFBUF | \
      ADAS1000.MASK_ECGCTL_CLKEXT | \
      ADAS1000.MASK_ECGCTL_MASTER | \
      ADAS1000.MASK_ECGCTL_GANG | \
      ADAS1000.MASK_ECGCTL_HP


Can you indicate me if my register configuration is correct or I need to change something for get the desired functionality.
