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. 92 Peripheral Information and Electrical Specifications Copyright © 2010, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): AM1808 |
