Description Probable Cause
Environment
Ambient temperature exceeded operating
temperature range
Permanent corruption of the content in
non-volatile memory occurred
A problem occurred when attempting to
write to the non-volatile memory
A problem occurred when attempting to
write to the non-volatile memory
A problem occurred when testing the
non-volatile memory
A problem occurred when testing the
non-volatile memory
A corruption of the content in non-volatile
memory occurred
The firmware checksum was invalid due
to data corruption
The micro-controller failed an operation
A problem with the memory stack
occurred
Raw write to FRAM
Technical fault to indicate a factory-only
operation
Device recovered after reset
An illegal circuit board interrupt occurred
