The

DPU Bus

Card waited for a response from the Control

Processor (CP) which was never received, and the CP reported no
other fatal alarm condition.

The

DPU Bus

Card waited for a response from the CP which was

never received because the CP determined that its program code
had been corrupted (checksum error).

The

DPU Bus

Card waited for a response from the CP which was

never received because the CP re-executed its startup code
unexpectedly (jump or return to address 0).
