PRODUCTION DATA.
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. Note that a lower number means higher priority — PRI = 000b = urgent, PRI = 111b = low.
All other masters provide their priority directly and do not need a default priority setting. Examples include the C66x 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.
The Packet DMA secondary port is one master port that does not have priority allocation register inside the Multicore Navigator. The priority level for transaction from this master port is described by the QM_PRIORITY bit field in the CHIP_MISC_CTL0 register shown in Section 10.2.3.24.
For all other modules, see the respective User's Guides listed in Section 12.3 for programmable priority registers.
