Description
Set to logic 1, this bit clears the temperature error, if the temperature
is below the alarm limit of 125 °C.
I
High-speed mode independent of the I
I
Reserved for future use.
Set to logic 1 if the Select command or if the Polling command was
answered. Note: This bit can only be set during the AutoColl
command in Passive Communication mode.
Note: This bit is cleared automatically by switching off the external
RF field.
This bit indicates that the MIFARE Crypto1 unit is switched on and
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 cards. This bit shall be cleared by software.
ModemState shows the state of the transmitter and receiver state
machines.
