I have Problem with the SEQERR- Bit in the Status1 Register.
If I connect 3 phases (each 100V) to the device it works fine.
When I disconnect, for example Phase 2, sometimes the SEQERR-Bit is set, sometimes it takes over 100ms until the ADE7880 reacts.
I didn't use the IRQ, but I write a "1" to the status1-Register after I have detected an error.
The bits, consel[1:0] in the ACCMODE Register are "0"
Attached you will find a screenshot,
Pink : High = Read Register of the ADE7880
Blue : Value toggel if the SEQERR bit is set
You see, sometimes it takes 180ms until I get the correct Information.
Can you help me ?
