PRODUCTION DATA.
Table 4-4 lists the GPIO pins and their analog and digital alternate functions. The AINx analog signals go through an isolation circuit before reaching their circuitry. These signals are configured by clearing the corresponding DEN bit in the GPIO Digital Enable (GPIODEN) register and setting the corresponding AMSEL bit in the GPIO Analog Mode Select (GPIOAMSEL) register. Other analog signals are 3.3-V tolerant and are connected directly to their circuitry (C0-, C0+, C1 -, C1+, C2-, C2+, USB0VBUS, USB0ID). These signals are configured by clearing the DEN bit in the GPIODEN register. The digital signals are enabled by setting the appropriate bit in the GPIO Alternate Function Select (GPIOAFSEL) and GPIODEN registers and configuring the PMCx bit field in the GPIO Port Control (GPIOPCTL) register to the numeric encoding shown in Table 4-4.
