This terminal can be configured as a GPIO or as the transmitter for a UART channel. This pin defaults to a general purpose output. This terminal can be configured as a GPIO or as the receiver for a UART channel. This pin defaults to a general purpose output. Configurable as general purpose input/outputs Pulse Width Modulation (PWM). Can be used to drive status LED's. PWM pull down resistors are disabled by default. A firmware modification is required to turn them on. [. . . ] All products are sold subject to TI's terms and conditions of sale supplied at the time of order acknowledgment.
