PRODUCTION DATA
Some pins on the device have internal pullups or pulldowns. Table 6-9 lists the pull direction and when it is active. The pullups on GPIO pins are disabled by default and can be enabled through software. To avoid any floating unbonded inputs, the Boot ROM will enable internal pullups on GPIO pins that are not bonded out in a particular package. Other pins noted in Table 6-9 with pullups and pulldowns are always on and cannot be disabled.
