There is a register used for controlling the priority of the MLB sub-system on the L3_MAIN. This is done through the CTRL_CORE_IP_PRESSURE register which reside in the CTRL_MODULE_CORE. The MLB has a default priority (pressure setting) on the L3_MAIN. To override the default setting the CTRL_CORE_IP_PRESSURE[2] MLB_L3_PRESSURE_ENABLE bit must be set to 0x1. When this is done the values configured through the CTRL_CORE_IP_PRESSURE[1:0] MLB_L3_PRESSURE bit field apply. Setting this bit field to 0x3 means that the MLB traffic has highest priority over the other initiator traffics. A value of 0x0 is for lowest priority.
