8 Modes of Operation
X-Mode
The easiest way to get started with the MIFARE SAM AV3 evaluation board is to operate the
MIFARE SAM AV3 in X-mode. See an example configuration below where the SAM can be accessed via
the I²C1 interface from the MCU, and will communicate to the CLRC663 via its host interface, configured as
I²C. The SAM VDD in below example is connected to IO6.
S-Mode
In this S-mode configuration, the MIFARE SAM AV3 is not connected to the CLRC663. The host MCU
controls the CLRC663 via the SPI interface, and the MIFARE SAM AV3 via I²C1.
