5.29 LSU Interrupt Condition Routing Registers (LSU_ICRR0–LSU_ICRR3)
SRIO Registers
Figure 90 shows the ICRRs for the LSU interrupt requests, and Table 81 shows the general description for
an ICRx field in any of the four registers. These registers route LSU interrupt requests from LSU_ICSR to
interrupt destinations. For example, if ICS4 = 1 in LSU_ICSR and ICR4 = 0000b in LSU_ICRR0, LSU1
has generated a transaction-timeout interrupt request, and that request is routed to interrupt destination 0.
For additional programming see Section 4.4.1.2 .
