However for this device, the priority control for the transfer controllers is controlled by the chip-level registers in the System Configuration Module. You should use the chip-level registers and not QUEPRI to configure the TC priority. 82 Peripheral Information and Electrical Specifications Copyright © 2008–2014, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320C6745 TMS320C6747 |
