a. The digital signals that are shaded gray are the power-on default values for the corresponding GPIO pin. Encodings 10-13 are not used
on this device.

Functional Description
Each GPIO port is a separate hardware instantiation of the same physical block (see Figure
10-1 on page 654 and Figure 10-2 on page 655). The TM4C123BH6ZRB microcontroller contains 15
ports and thus 15 of these physical GPIO blocks. Note that not all pins are implemented on every
block. Some GPIO pins can function as I/O signals for the on-chip peripheral modules. For information
on which GPIO pins are used for alternate hardware functions, refer to Table 22-5 on page 1277.
