Set to 1, turning on the driver in reader or active mode is
requested.
Note: According to the setting of InitialRFOn, AutoRFOn and
CAOn the driver is turned after a defined time and depended
on the presence of an external RF field.
Note: In case of an RFActiveError this bit is cleared by
hardware
Set to 1, enables automatic collision avoidance. See
ISO18092 for more details.
Set to 1, the drivers are automatically turned on when no
external field is present. In the case an external field is
detected, the turning on the drivers is delay until the external
field vanishes.
Note: The driver on procedure must be triggered by setting
TX_RF_ENABLE.
Note: This bit is reset to 0 as soon as the drivers turned on.
Set to 1, the drivers are automatically turned on after a
before present external field vanished.
Note: The driver on procedure must be triggered by setting
TX_RF_ENABLE.
Set to 1, the drivers are automatically turned off after data is
transmitted
