9.4 Bus Priorities

The priority level of all master peripheral traffic is defined at the TeraNet boundary. User programmable priority registers allow software configuration of the data traffic through the TeraNet. A lower number means higher priority - PRI = 000b = urgent, PRI = 111b = low.

Most master ports provide their priority directly and do not need a default priority setting. Examples include the CorePacs, whose priorities are set through software in the UMC control registers. All the packet-DMA-based peripherals also have internal registers to define the priority level of their initiated transactions.

Some masters do not have apriority allocation register of their own. For these masters, a priority allocation register is provided for them and described Section 9.4.1 and Section 9.4.2. For all other modules, see the respective User Guides in Section 10.3 for programmable priority registers.
