SRIO Registers

5.24Error, Reset, and Special Event Interrupt Condition Status Register (ERR_RST_EVNT_ICSR)

Each of the nonreserved bits in this register indicate the status of a particular interrupt condition in one or more of the SRIO ports. ERR_RST_EVNT_ICSR is shown in Figure 85 and described in Table 75. For additional programming information, see Section 4.3.4.
