The device system bus infrastructure arbitrates bus requests from all of the controllers (TCs, CPU(S), and other bus controllers) to the shared target resources (peripherals and memories).
The priorities of transfer requests (read and write commands) from the EDMA transfer controllers with respect to other controllers within the device VIM are fixed values part of interconnect: SOC_TC0_R, SOC_TC0_W, SOC_TC1_R, and SOC_TC1_W (from Initiator IDs). The EDMA_TPCC_QUEPRI register has no affect.
Therefore, the priority of unloading queues has a secondary affect compared to the priority of the transfers as they are executed by the EDMA_TPTC.
