Startup/HPMM failure sequence
An HPMM failure occurs during or after a Startup results in alternating failure and Communications
processor Hard failure code. This is dependent upon whether the Detailed Display mode (switch) is
enabled. The description in the following table is an example of a sequence when a spurious interrupt
failure occurs listing both the Detailed Display mode and non-Detailed Display mode.
