12.2 Signal Description
Table 12-1 on page 433 and Table 12-2 on page 434 list the external signals of the UART module
and describe the function of each. The UART signals are alternate functions for some GPIO signals
and default to be GPIO signals at reset, with the exception of the U0Rx and U0Tx pins which default
to the UART function. The column in the table below titled "Pin Assignment" lists the possible GPIO
pin placements for these UART signals. The AFSEL bit in the GPIO Alternate Function Select
(GPIOAFSEL) register (page 309) should be set to choose the UART function. For more information
on configuring GPIOs, see “General-Purpose Input/Outputs (GPIOs)” on page 287.
