Commands
Enhanced buffered write configuration (EC)
Command:
Response:
The R/W head attempts to write a word in the configuration range to the address
<ConfAddr> until successful. After each write, the status is evaluated and the
system waits until a new data carrier is within the detection range. The command
then starts again from the beginning. In order to write in the configuration range,
the password mode must be active.
The status '05h' (read/write command) is only output when a data carrier leaves
the detection range or 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.
