Pulse Width Modulator (PWM)
signals at reset. The column in the table below titled "Pin Mux/Pin Assignment" lists the possible
GPIO pin placements for these PWM signals. The AFSEL bit in the GPIO Alternate Function Select
(GPIOAFSEL) register (page 429) should be set to choose the PWM function. The number in
parentheses is the encoding that must be programmed into the PMCn field in the GPIO Port Control
(GPIOPCTL) register (page 447) to assign the PWM signal to the specified GPIO port pin. For more
information on configuring GPIOs, see “General-Purpose Input/Outputs (GPIOs)” on page 405.
