Diagnostic Parameter Register
The diagnostic parameter register provides additional
information about the error that is indicated in the diagnostic
status register. This is either
the error location (in the case of bus errors) or
the error code.
Figure 31
Diagnostic parameter register
Special case: If a local bus error cannot be located,
byte n+1 of the diagnostic parameter register (error
location) indicates the value 128 or bit 7 is set.
The error is in the local bus segment indicated.
Whenever an error bit is set, the 16-bit diagnostic parameter
register is rewritten. If no error bit is set, the register has the
value 0.
For further information please refer to the
IBS SYS DIAG DSC UM E Diagnostics Guide.
