Preliminary Technical Data
ADuC7032
GPIO Port2 Clear Register :
Name :
GP2CLR
Address :
0xFFFF0D48
Default Value : 0x00000000
Access :
Read/Write
Function :
This 32-bit MMR allows user code to individually bit address external GPIO pins to clear them low only.
User code can do this via the GP2CLR MMR without having to modify or maintain the status of any other GPIO
pins as user code would need to do when using GP2DAT.

Description
Reserved
These bits are reserved and should be written as 0 by user code
Port 2.6 Clear Bit
This bit is set to 1 by user code to clear the external GPIO13 pin low.
If user software clears this bit to 0, this will have no effect on the external GPIO8 pin.
Port 2.5 Clear Bit
This bit is set to 1 by user code to clear the external GPIO12 pin low.
If user software clears this bit to 0, this will have no effect on the external GPIO7 pin.
Reserved
These bits are reserved and should be written as 0 by user code
Port 2.1 Clear Bit
This bit is set to 1 by user code to clear the external GPIO8 pin low.
If user software clears this bit to 0, this will have no effect on the external GPIO8 pin.
Port 2.0 Clear Bit
This bit is set to 1 by user code to clear the external GPIO7 pin low.
If user software clears this bit to 0, this will have no effect on the external GPIO7 pin.
Reserved
These bits are reserved and should be written as 0 by user code
