4.3.9 Command 0x09 - Set / Get Device Configuration
The host calls this command in Set mode to send operator-defined configuration settings to the device. If
the command changes the EMV Mode control setting, the host must send
Command 0xFF - Device
Reset or the operator must power cycle the device before that setting takes effect.
The host can also call this command in Get mode to direct the device to return its current configuration
settings. The format of the device’s response in this case is identical to the format of the host’s request
when calling the command in Set mode (
Table 4-10 ).
If an error occurs, the device terminates the command and reports the error in ACKSTS of
Command
0x01 - Response ACK . For a full list of error codes, see Command 0x01 - Response ACK .
If no error occurs, the device saves the new configuration.
