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 Fig 42 for SWP state tran
sition.
9.5.2 Examples of communication with the UICC connected via SWP
9.5.2.1 Card emulation use case
The ho
st 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.
