SRIO Registers
5.27 RX CPPI Interrupt Condition Routing Registers (RX_CPPI_ICRR and RX_CPPI_ICRR2)
Figure 88 and Table 79 summarize the ICRRs for the RXU. These registers route queue interrupts to interrupt destinations. For example, if ICS6 = 1 in RX_CPPI_ICSR and ICR6 = 0010b in RX_CPPI_ICRR, the interrupt request from RX buffer descriptor queue 6 is sent to interrupt destination 2. For additional programming see Section 4.4.1.1.
