Unrecoverable errors detected by the Q53 firmware force it into panic mode. Manually 
reset the Q53 to resume normal operation.

The watchdog timer is a hardware device that resets the system if not serviced regularly 
by the CPU. It’s purpose is to prevent the CPU from entering an infinite loop because of 
a hardware or firmware problem. After a watchdog interrupt, some diagnostic 
information is saved for debugging and the device resumes operation in Auto-reset 
Mode. The Q53 will auto-reset up to 16 times before entering non-operational Watchdog 
Halt.

Unsupported interrupts force the Q53 into this non-operational mode and typically 
indicate a hardware problem.

Internal errors such as bus errors, address errors or illegal instructions force the Q53 into 
this non-operational mode.
