Table 12-3. EPC Control Register (EPCCNTRL) Field Descriptions
Bit Field Value Description
31-25 Reserved 0 Reserved. Reads return 0.
24 CAM/FIFO_FULL_ENA CAM or FIFO full interrupt enable. If this bit is set and CAM is full, CAM Full Interrupt
is generated.
Read:
0 CAM/FIFO full interrupt is disabled.
1 CAM/FIFO full interrupt is enabled.
Write in Privilege:
0 Disable CAM/FIFO full interrupt.
1 Enable CAM/FIFO full interrupt.
23-12 Reserved 0 Reserved. Reads return 0.
11-8 DIA_ENA_KEY CAM diagnostic enable key. These bits (when enabled) allow the CPU to access the
CAM content to clear or set any entry (CAM index) or write any pattern to CAM
content.
Internal RTL will implement self-correction logic to avoid single bit flipping.
Read:
5h CAM diagnostic is disabled.
Ah CAM diagnostic is enabled.
All other values Reserved
Write in Privilege:
5h CAM diagnostic is disabled.
Ah CAM diagnostic is enabled.
All other values Reserved
7-4 Reserved 0 Reserved. Reads return 0.
3-0 SERRENA Single (correctable) bit error event enable. These bits (when enable) cause EPC to
generate the serr_event if there is a correctable ECC fault address arrives from one of
the EPC-IP interface and the CAM has an empty entry. These bits also allow EPC to
generate the serr_event if there is a correctable ECC fault address arrives from one of
the EPC-IP interface and the CAM is full. In this case, CAM FULL status bit is set in
EPCERRSTAT.
Internal RTL will implement self-correction logic to avoid single bit flipping.
Read:
5h serr_event generation is disabled.
Ah serr_event generation is enabled.
All other values Reserved
Write in Privilege:
5h serr_event generation is disabled.
Ah serr_event generation is enabled.
All other values Reserved
