a. The digital signals that are shaded gray are the power-on default values for the corresponding GPIO pin.
9.2 Functional Description
Each GPIO port is a separate hardware instantiation of the same physical block (see Figure
9-1 on page 407 and Figure 9-2 on page 408). The LM3S5P36 microcontroller contains five ports and
thus five of these physical GPIO blocks. Note that not all pins may be 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 980.
