Enhanced buffered get configuration (EG):
Command:
Response:
The R/W head attempts to read a word in the configuration range from the address
<ConfAddr> 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/write command) is output when the data carrier leaves the detection
range or if the data carrier is not yet within the detection range when the command is executed.
If two data carriers enter the read range one immediately after the other, the status '05h' is not
issued between the two readings.
