CLRC632
Standard multi-protocol reader solution
9.13 ISO/IEC 14443 B communication scheme
The international standard ISO/IEC 14443 covers two communication schemes; ISO/IEC
14443 A and ISO/IEC 14443 B. The CLRC632 reader IC fully supports both ISO/IEC
14443 variants.
Table 35 describes the registers and flags covered by the ISO/IEC 14443 B
communication protocol.
