Description
GPIO Port P Power Control
The Pn bit encodings are not applicable if the corresponding bit in the
RCGCGPIO, SCGCGPIO or DCGCGPIO register is clear.
Value Description
0 GPIO Port P 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.
1 GPIO Port P is powered, but does not receive a clock. In this
case, the module is inactive.
1
GPIO Port N Power Control
The Pn bit encodings are not applicable if the corresponding bit in the
RCGCGPIO, SCGCGPIO or DCGCGPIO register is clear.
Value Description
0 GPIO Port N 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.
1 GPIO Port N is powered, but does not receive a clock. In this
case, the module is inactive.
1
GPIO Port M Power Control
The Pn bit encodings are not applicable if the corresponding bit in the
RCGCGPIO, SCGCGPIO or DCGCGPIO register is clear.
Value Description
0 GPIO Port M 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.
1 GPIO Port M is powered, but does not receive a clock. In this
case, the module is inactive.
1
GPIO Port L Power Control
The Pn bit encodings are not applicable if the corresponding bit in the
RCGCGPIO, SCGCGPIO or DCGCGPIO register is clear.
Value Description
0 GPIO Port L 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.
1 GPIO Port L is powered, but does not receive a clock. In this
case, the module is inactive.
