Write only
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 GPCLR MMR without having to modify or maintain the status of any other GPIO pins
(as user code requires when using GPDAT).
Description
Reserved. These bits are reserved and should be written as 0 by user code.
Port 0.5 clear bit.
This bit is 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.
Port 0.4 clear bit.
This bit is set to 1 by user code to clear the external GPIO_4 pin low.
If user software clears this bit to 0, it has no effect on the external GPIO_4 pin.
Port 0.3 clear bit.
This bit is set to 1 by user code to clear the external GPIO_3 pin low.
If user software clears this bit to 0, it has no effect on the external GPIO_3 pin.
Port 0.2 clear bit.
This bit is set to 1 by user code to clear the external GPIO_2 pin low.
If user software clears this bit to 0, it has no effect on the external GPIO_2 pin.
Port 0.1 clear bit.
This bit is set to 1 by user code to clear the external GPIO_1 pin low.
If user software clears this bit to 0, it has no effect on the external GPIO_1 pin.
Port 0.0 clear bit.
This bit is set to 1 by user code to clear the external GPIO_0 pin low.
If user software clears this bit to 0, it has no effect on the external GPIO_0 pin.
Reserved. These bits are reserved and should be written as 0 by user code.
