8.8 Sleep mode
If the sleep mode is enabled (see configuration bit Table 9) and the electronic device (e.g.
a microcontroller) connected to the NTAG21xF device brings the Field detection pin to
GROUND and the NFC device triggers RF reset, then the NTAG21xF device will enter
into the sleep mode where it will become invisible for the NFC device (e.g. phone).
This mode is only effective after RF reset, i.e. even if the Field detect pin is brought to
ground during HF communication, this will have no impact on the ongoing device
activities.
See Ref. 8 for additional information and Table 41 for the voltage range to be applied on
the field detection pin for effective sleep mode.
The Field detect pin shall not be left floating.
