Commands
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.
