PRODUCTION DATA
Each GPIO pin can has a input disable and a pulldown disable. By default, the GPIO pin input paths are enabled and the internal pulldown circuit in the GPIO is enabled. The GPIO_INPUT_CTL register 0x0F (Table 7-33) and GPIO_PD_CTL register 0xBE (Table 7-176) allow control of the input enable and the pulldown, respectively. For most applications, there is no need to modify the default register settings.
