3.4.5.3 CPU Program Fetch Aborts

If the PBU has read an uncorrectable value from the PBU or SRAM memory (DED status is 1), then the data should not be consumed by the CPU. In this case, the PBU or SRAM will indicate that the data is not ready, which will stall the CPU. At that time, a trap event for an uncorrectable DED error should occur. The trap event will abort the bad data fetch and cause the CPU to vector to the trap handler.
