Error Type
The next bits indicate the type of detected error:
  • Bit 0 =1: Module or bus
  • Bit 1 =1: Missing slave(s)
  • Bit 2 =1: Not configured slave(s)
  • Bit 3 =1: Slaves
STGENE
WORD
Module or bus error
Detail of the detected module or bus error:

Diagnostic Viewer
The Diagnostic Viewer uses an instance of a ASI_DIA DFB to display information about AS-Interface bus detected errors.
Diagnostic Viewer illustration:
There are 2 areas in the Diagnostic Viewer:
