The DEVICE CONFIGURATION FREEZE LOCK command prevents accidental modification of the Device
Configuration Overlay settings. After successful execution of a DEVICE CONFIGURATION FREEZE LOCK
command, all DEVICE CONFIGURATION SET, DEVICE CONFIGURATION FREEZE LOCK, DEVICE
CONFIGURATION IDENTIFY, and DEVICE CONFIGURATION RESTORE commands are aborted by the
device. The DEVICE CONFIGURATION FREEZE LOCK condition is cleared by a power-down. The
DEVICE CONFIGURATION FREEZE LOCK condition is not cleared by hardware or software reset.
If the device has executed a previous DEVICE CONFIGURATION FREEZE LOCK command since power-up, the
device returns command aborted.
