SRIO Registers
5.40 LSUn Congestion Control Flow Mask Register (LSUn_FLOW_MASKS)
There are four of these registers, one for each LSU (see Table 101). The fields of an
LSUn_FLOW_MASKS register are summarized by Figure 101 and described in Table 102. The 16 bits within each FLOW_MASK field are summarized by Figure 102 and Table 103. For additional programming see Section 2.3.8.
