Texas Instruments TM4C1294NCPDT User Manual

placements for these UART signals. The AFSEL bit in the GPIO Alternate Function Select
(GPIOAFSEL) register (page 770) should be set to choose the UART function. The number in
parentheses is the encoding that must be programmed into the PMCn field in the GPIO Port Control
(GPIOPCTL) register (page 787) to assign the UART signal to the specified GPIO port pin. For more
information on configuring GPIOs, see “General-Purpose Input/Outputs (GPIOs)” on page 742.
