GPIO Port1 Clear Register
Name:
GP1CLR
Address:
0xFFFF0D38
Access:
Write only
Function:
This 32-bit MMR allows user code to individually bit-address external GPIO pins to clear them low only. User code
can accomplish this using the GP1CLR MMR without having to modify or maintain the status of any other GPIO pins
(as user code requires when using GP1DAT).
Table 69. GP1CLR 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 Clear Bit.
Set to 1 by user code to clear the external GPIO_6 pin low.
If user software clears this bit to 0, it has no effect on the external GPIO_6 pin.
16
Port1.0 Clear Bit.
Set to 1 by user code to clear the external GPIO_5 pin low.
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.
GPIO Port2 Clear Register
Name:
GP2CLR
Address:
0xFFFF0D48
Access:
Write only
Function:
This 32-bit MMR allows user code to individually bit-address external GPIO pins to clear them low only. User code
can accomplish this using the GP2CLR MMR without having to modify or maintain the status of any other GPIO pins
(as user code requires when using GP2DAT).

Bit
Description
31 to 23
Reserved. These bits are reserved and should be written as 0 by user code.
22
Port2.6 Clear Bit.
Set to 1 by user code to clear the external GPIO_13 pin low.
If user software clears this bit to 0, it has no effect on the external GPIO_8 pin.
21
Port2.5 Clear Bit.
Set to 1 by user code to clear the external GPIO_12 pin low.
If user software clears this bit to 0, it has no effect on the external GPIO_7 pin.
20 to 18
Reserved. These bits are reserved and should be written as 0 by user code.
17
Port2.1 Clear Bit.
Set to 1 by user code to clear the external GPIO_8 pin low.
If user software clears this bit to 0, it has no effect on the external GPIO_8 pin.
16
Port2.0 Clear Bit.
Set to 1 by user code to clear the external GPIO_7 pin low.
If user software clears this bit to 0, it has no effect on the external GPIO_7 pin.
15 to 0
Reserved. These bits are reserved and should be written as 0 by user code.
