Resolution
CATERR stands for Catastrophic Error, it is part of thermal protection signales. The CATERR# indicates that the system has experienced a catastrophic error and cannot continue to operate. The processor will set this signal for non-recoverable machine check errors or other unrecoverable internal errors. CATERR# is used for signaling the following types of errors:
- Legacy MCERRs (Machine check errors) , CATERR# is asserted for 16 base blocks (BCLKs).
- Legacy IERRs (internal errors) , CATERR# remains asserted until warm or cold reset.
