Response:
The R/W head attempts to read a special read only code until successful. Only
data that changes is transferred via the interface, i.e. the R/W head transfers data
whenever it reads a new data carrier or whenever it reads a data carrier where
there was previously no R/W head within the detection range.
The status '05h' (read command) is output whenever a data carrier leaves the
detection range.
