3.0. Architecture
AT90SCR is for main processor for communication with PC, and control the contactless chip,
communication with SAM card and peripherals. PN512 act as a contactless chip to perform the
communication between contactless tags and AT90SCR
For communication architecture, the protocol between ACR1251U and PC is using CCID protocol.
The communication between SAM is PCSC Compliant
