The ICSR and the ICCR for the SRIO ports are shown in
Figure 53
. As described in
Table 37
, each of the
nonreserved status and clear bits corresponds to a particular interrupt condition in one or more of the
SRIO ports. The ICS bits of ERR_RST_EVNT_ICSR indicate the occurrence of the conditions. The ICC
bits of ERR_RST_EVNT_ICCR are used to clear the corresponding ICS bits.
