XS - Mode
In this configuration, the CLRC663 is connected on its host interface via SPI to the MCU, and
on the second interface via I²C to the SAM. The MIFARE SAM AV3 is connected via I²C1 to
the MCU. In this way, the MCU can control the CLRC663's LPCD procedure, and if a card is
detected, the SAM can be switched on and take over the control over the CLRC663.
ISO7816 Interface
In this configuration, the MIFARE SAM AV3 is controlled via the ISO7816 Interface which is
available on the 16-pin header CN5. The pinning is compatible to the GMMC ISO7816 to
SIM SAM Adapter which also can be used stand-alone in case the SIM sized SAM is used.
