Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

GPIO Port T Power Control
The Pn bit encodings are not applicable if the corresponding bit in the
RCGCGPIO, SCGCGPIO or DCGCGPIO register is clear.
DescriptionValue
GPIO Port T is not powered and does not receive a clock. In
this case, the module's state is not retained.
This configuration provides the lowest power consumption state.
0
GPIO Port T is powered, but does not receive a clock. In this
case, the module is inactive.

GPIO Port S Power Control
The Pn bit encodings are not applicable if the corresponding bit in the
RCGCGPIO, SCGCGPIO or DCGCGPIO register is clear.
DescriptionValue
GPIO Port S is not powered and does not receive a clock. In
this case, the module's state is not retained.
This configuration provides the lowest power consumption state.
0
GPIO Port S is powered, but does not receive a clock. In this
case, the module is inactive.

GPIO Port R Power Control
The Pn bit encodings are not applicable if the corresponding bit in the
RCGCGPIO, SCGCGPIO or DCGCGPIO register is clear.
DescriptionValue
GPIO Port R is not powered and does not receive a clock. In
this case, the module's state is not retained.
This configuration provides the lowest power consumption state.
0
GPIO Port R is powered, but does not receive a clock. In this
case, the module is inactive.

GPIO Port Q Power Control
The Pn bit encodings are not applicable if the corresponding bit in the
RCGCGPIO, SCGCGPIO or DCGCGPIO register is clear.
DescriptionValue
GPIO Port Q is not powered and does not receive a clock. In
this case, the module's state is not retained.
This configuration provides the lowest power consumption state.
0
GPIO Port Q is powered, but does not receive a clock. In this
case, the module is inactive.
