6.2 Catastrophic Error Sensor
When the Catastrophic Error signal (CATERR#) stays asserted, it is a sign that something serious has gone wrong in the hardware.
The BMC monitors this signal and reports when it stays asserted.

[7:6] – 10b = OEM code in Event Data 2
[5:4] – 10b = OEM code in Event Data 3
[3:0] – Event Trigger Offset = 1h (State Asserted)

Event Data 3
Bitmap of the CPU that causes the system CATERR.
[0]: CPU1
[1]: CPU2
[2]: CPU3
[3]: CPU4
Note: If more than one bit is set, the BMC cannot
determine the source of the CATERR.
