The information required to analyze an error source is logged in several registers. The number of registers to access depends on the error source.
Figure 14-15 shows the software sequence required in most cases.
L4 interconnects don't log any address or other specific information for a custom error returned from any target IP. They rather pass an error response up to the master supposed to analyze it.
In case of posted writes, the master access completes before it actually completed at the end slave level, this way no error response is sent back to the master, making it impossible to have a direct way of uderstanding the origin of L4 error during posted writes. However, even though no address is logged, an error flag is generated and needs to be processed.
