Description
Set to logic 1, this bit clears the temperature error, if the temperature
is below the alarm limit of 125 °C.
I
Set to logic 1, the I
independent of the I
Set to logic 0, the I
Reserved for future use.
This bit indicates that the MIFARE
therefore all data communication with the card is encrypted.
This bit can only be set to logic 1 by a successful execution of the
MFAuthent Command. This bit is only valid in Reader/Writer mode
for MIFARE
ModemState shows the state of the transmitter and receiver state
machines.
