ADAS1000-1 Fault bit of FRAMES register question

Hi,

I'm using two ADAS1000-1 for getting 12 leads. Every time I initialize two chips and start measuring after power on, the Fault bit of FRAMES register( 0x40[27] ) will be set. If I stop measuring by reset CNVEN bit of ECGCTL register and then start measuring again, it's OK. Once the Fault bit is set, the ECG data of V1 electrode is zero though the V1EN bit of ECGCTL is set.

 

Questions:

1. Which part is abnormal when the Fault bit is set?

2. Why Fault bit is set in first time initialization after power on?

3. How can I solve this problem?
