SRIO Registers

5.30 Error, Reset, and Special Event Interrupt Condition Routing Registers (ERR_RST_EVNT_ICRR, ERR_RST_EVNT_ICRR2, and ERR_RST_EVNT_ICRR3)

The ICRRs shown in Figure 91 route port interrupt requests from ERR_RST_EVNT_ICSR to interrupt destinations. For example, if ICS8 = 1 in ERR_RST_EVNT_ICSR and ICR8 = 0001b in ERR_RST_EVNT_ICRR2, port 0 has generated an error interrupt request, and that request is routed to interrupt destination 1. Table 82 gives a general description for an ICRx field in any of the three registers. For additional programming see Section 4.4.1.3.
