Improving RF reception for FeliCa™ tags

To improve ST25R95 reception when communicating with FeliCa™ tags, it is possible to enable an AutoDetect

filter to synchronize FeliCa™ tags with the ST25R95. This can be done using the Write Register (WrReg)

command to enable the AutoDetect filter.

By default, this filter is disabled after the execution of the ProtocolSelect command, but it can be enabled using

the WrReg command (0x09).
