Problem reference code formats detected by Licensed Internal Code
Use this information to understand problem reference code formats that are detected by Licensed Internal
Code.
Formats 60 - 63 in Table 4 on page 18 represent the formats for Licensed Internal Code SRCs.
v Format 60 is used for Licensed Internal Code attention SRCs.
v Format 61 is used when Licensed Internal Code detects a Licensed Internal Code programming
problem.
v Format 62 is used when Licensed Internal Code detects an IOP bus or IOP programming problem.
RRRR Licensed Internal Code unit reference code.
cccc Licensed Internal Code component reference Code. Identifies the Licensed Internal Code component
and subcomponent that generated the SRC.
pppp Licensed Internal Code program reference code (PRC). Identifies the Licensed Internal Code class or
component that generated the SRC and the specific error detected.
qqqq Licensed Internal Code program reference code qualifier. Identifies SRC words found at functions
15-3 through 19-3 or, 15-3 and 16-3, depending on the format. It provides additional error
isolation information that is specific to the program reference code. One or more of these words
might be 0000 0000. Format 61 has up to five words of PRC qualifier, in words5-9.ThePRC
determines the number of PRC qualifer words. The content of words5-9isdependent on the
value in word 4. Format 62 has the PRC qualifier only in words5-6.Physical address and type
information is included in words7-9.

@@@@ Unit address.
ssss Serial number of failing unit.
TTTT Type number or card identification number of failing component (hex 2xxx - 9FFF). This value
might be 0000 if system data is not available at the time the SRC is signaled.
