Error information
• DEVICE CONFIGURATION RESTORE (FR=C0h)
The DEVICE CONFIGURATION RESTORE command disables any setting
previously made by a DEVICE CONFIGURATION SET command and
returns the content of the IDENTIFY DEVICE command response to the
original settings as indicated by the data returned from the execution of a
DEVICE CONFIGURATION IDENTIFY command. After execution of this
command, the settings are kept for the device power down or reset.
If a Host Protected Area has been set by a SET MAX ADDRESS (EXT)
command, or if DEVICE CONFIGURATION FREEZE LOCK is set, an
aborted error is posted.
• DEVICE CONFIGURATION FREEZE LOCK (FR=C1h)
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, not cleared by a hardware or software
reset.
If the device has executed a previous DEVICE CONFIGURATION FREEZE
LOCK command since power-up, an aborted error is posted.
