Note: If Host wants to enable these registries change, it has to force the UICC re-
initialization, by setting the
UICC_AdminSessionId EEPROM
area to its default value.
Host has also to take care of UICC power reset to ensure the settings change. This
command has to be sent before
NXP_SWP_DEFAULTMODE
use for enabling SWP link.
9.5.1.6 Reading SWP status
SWP status can be read, using
NXP_SWP_STATUS Id ‘02’
of the registry.
See
for SWP state transition.
9.5.2 Examples of communication with the UICC connected via SWP
9.5.2.1 Card emulation use case
The host shall set the parameters of the
SwpMgt
gate as described in the previous
paragraph.
The UICC shall behave as described in HCI specification.
•
The UICC creates and open the pipe between the card gates and card RF gates.
•
The UICC activates one or more RF technology. UICC updates the parameters of the
corresponding registry.
−
Example for RF technology Type A: The UICC updates UID, SAK, ATQA,
APPLICATION_DATA, FWI parameters. Then it sets MODE ‘02’ (i.e. enable). The
PN544 is then able to handle the initialization and anti-collision phase by itself.
