在Parallel Interface Mode下一二次側均為High時,VACC突然斷電;依照規額書說明二次側會保留斷電前一刻動作,
請問有什麼方法可以在斷電時讓二次側一同拉Low ??
或是讓MCU知道VACC已經斷電異常 ??

The ISO1228 will generate a fault on the nFAULT pin if any fault is detected. The exact fault can be read in serial mode to detect if there was a field side power loss.(See 7.3.5 FAULT Indication and https://www.ti.com/lit/pdf/slla640) for more details.
