Page 6: Use Of The Evaluation Kit In Active Mode
To avoid the conflict of two power sources in case of NFC field presence – the NFC field should not present at the moment when NAC1080 is powering up from VCC– that is, a reader (a cell phone) has to be removed from the antenna of the evaluation board at the moment of NAC1080 startup and in this case the IC keeps the supply status (active mode) until the next power-down cycle. -
