Description
indicates current software version of the MFRC522
Remark: the current version of the MFRC522 is 90h or 91h
reserved for production tests
internal signal processing in the receiver chain is performed
non-linearly which increases the operating distance in communication
modes at 106 kBd
Remark: due to non-linearity, the effect of the RxThresholdReg
register’s MinLevel[3:0] and the CollLevel[2:0] values is also
non-linear
reserved for production tests
enables the digital self test
the self test can also be started by the CalcCRC command; see
Section 10.3.1.4 on page 68
the self test is enabled by 1001b
Remark: for default operation the self test must be disabled by 0000b
