GPIO Port0 Set Register
Name: GP0SET
Address: 0xFFFF0D24
Access: Write only
Function: This 32-bit MMR allows user code to individually bit address external GPIO pins to set them high only. User code can
accomplish this using the GP0SET MMR without having to modify or maintain the status of any other GPIO pins (as
user code requires when using GP0DAT).
Table 65. GP0SET MMR Bit Designations
Bit Description
31 to 21 Reserved. These bits are reserved and should be written as 0 by user code.
20 Port0.4 Set Bit.
Set to 1 by user code to set the external GPIO_4 pin high.
If user software clears this bit to 0, it has no effect on the external GPIO_4 pin.
19 Port0.3 Set Bit.
Set to 1 by user code to set the external GPIO_3 pin high.
If user software clears this bit to 0, it has no effect on the external GPIO_3 pin.
18 Port0.2 Set Bit.
Set to 1 by user code to set the external GPIO_2 pin high.
If user software clears this bit to 0, it has no effect on the external GPIO_2 pin.
17 Port0.1 Set Bit.
Set to 1 by user code to set the external GPIO_1 pin high.
If user software clears this bit to 0, it has no effect on the external GPIO_1 pin.
16 Port0.0 Set Bit.
Set to 1 by user code to set the external GPIO_0 pin high.
If user software clears this bit to 0, it has no effect on the external GPIO_0 pin.
15 to 0 Reserved. These bits are reserved and should be written as 0 by user code.
GPIO Port1 Set Register
Name: GP1SET
Address: 0xFFFF0D34
Access: Write only
Function: This 32-bit MMR allows user code to individually bit-address external GPIO pins to set them high only. User code can
accomplish this using the GP1SET MMR without having to modify or maintain the status of any other GPIO pins (as
user code requires when using GP1DAT).
Table 66. GP1SET MMR Bit Designations
Bit Description
31 to 18 Reserved. These bits are reserved and should be written as 0 by user code.
17 Port1.1 Set Bit.
Set to 1 by user code to set the external GPIO_6 pin high.
If user software clears this bit to 0, it has no effect on the external GPIO_6 pin.
16 Port1.0 Set Bit.
Set to 1 by user code to set the external GPIO_5 pin high.
If user software clears this bit to 0, it has no effect on the external GPIO_5 pin.
15 to 0 Reserved. These bits are reserved and should be written as 0 by user code.
