Figure 25: Error Management Block Architecture
The Error Log is a 256 entry buffer which captures detected events that have reporting enabled, as described in Event
Notification . Each error log buffer entry consists of an event source, an event group, and an error type. The encoding of event
source and error type is captured in the following sections.
The device provides eight Error Log Match Register {0..7} that can be configured to detect when specific events are reported to
the Error Log. While these registers have many functions related to notification, they also determine if an event feeds the Error
Log Events Register . If the counter reaches its maximum value, 0xFFFF, this constitutes a reportable event.
If the event selected by a Error Log Match Register {0..7} is detected, then the bit in the Error Log Match Status Register
associated with that Error Log Match Register {0..7} is set. Setting bits in the Error Log Match Status Register does not
constitute an event, but does inform the user which Error Log Match Register {0..7} has detected an event.
6.2.9.1 Error Log Event Source Encoding
Each functional block that supports the error reporting function is defined as an “Event Source”. The CPS-1848 allows the user
to enable and disable the error reporting functionality of each of these sources. Regardless of whether or not reporting is
enabled, all errors that are received by the Error Management Block are stored in the Error Log. The list of non-S-RIO error
sources and their respective codes is provided in
Table 43 .
